===x64sc===
==Trunk==


x64sc, the next step in C64 emulation. (merged before 2.2.2)
Here is a short overview of all changes made in trunk that are relevant for the respective port/gui maintainers.


Disable on low-end ports
Note: '''new stuff should be added at the bottom and each item should have the related svn revision'''
* x64sc needs a lot of host CPU and reSID-fp
* TODO: Disable building x64sc for: gp2x, riscos (any others?)


UI rework
To keep the size of this list down (and hopefully shrinking) ...
* UI for x64sc using c64scui_init/shutdown, differences listed below
* See SDL UI and/or *nix UIs for an example and suggested menu item naming
* TODO: New UI for: amiga, beos, msdos, os/2, osx


* C64
* Port/GUI Maintainers should remove their port from the respective item when it is implemented.  
** Overall model selection, see c64/c64model.h
* To not clutter this page with stuff that will not get implemented anytime soon ("i will not add lightpen support to this handheld port") in such cases the respective port should also get removed from the respective item, and a note pointing out the missing feature should get added to [[Todo#Ports_.2F_UIs]] instead.
** NOTE: The C64 model selection affects (and is affected by) all the resources listed below plus the SID model (and engine, if not reSID-fp already)
* Items which have no more TODOs left should then be moved to the [[Developer_log_old]] Page
** TODO: UI items for: amiga, beos, msdos, os/2, osx
* CIA
** Resource: CIA1Model (toggle or enum with 0 & 1)
** Resource: CIA2Model (toggle or enum with 0 & 1)
** NOTE: could be used also in x64 and x128, probably not worth the hassle
** TODO: UI items for: amiga, beos, msdos, os/2, osx
* VICII
** Resource: VICIIModel (enum, see vicii.h)
** NOTE: NTSC models not implemented yet
** TODO: UI items for: amiga, beos, msdos, os/2, osx
* System
** Resource: GlueLogic (toggle or enum with 0 & 1, possibly more if variations found)
** TODO: UI items for: amiga, beos, msdos, os/2, osx
* PAL/NTSC
** Remove/disable the PAL/NTSC/oldNTSC items from the VICII menu (handled via VICIIModel or overall model instead)
** TODO: Remove/disable UI items for: amiga, beos, msdos, os/2, osx


Config split
----
* Datadir uses machine_name as before, config/hotkeys/fliplist/etc (should) use machine_get_name() instead


* Use "C64SC" for x64sc
===r34242===
** NOTE: data/C64 is still used for x64sc
** TODO: check config/etc file names/usage for: osx, win32
* Use "VSID" for vsid
** Due to the config split, it is finally possible to have VSID config/hotkeys/etc
** TODO add load/save settings and tweak the ifndef on main.c for: amiga, beos, msdos, os/2, osx, win32
* Use "CBM-II-5x0" for xcbm2 -model 510
** Should get rid of segfaults when using different models with same config
** TODO: check config/etc file names/usage for: osx, win32


===trunk===
* added tapecart emulation, still needs GUI hookups


* chris/v2.1-quicktime [2.1.2]
Tapecart support has been added in the Gtk3 UI and the SDL UI, including a 'flush image button' which uses the new tapecart_flush_tcrt() function in tapecart.c.
** NEW: added QuickTime movie exporter (on Mac OS X for now)
** API: introduced new soundmovie.c sound exporter
** API: gfxoutput.h: extended interace of gfxoutputdrv_t
gfxoutputdrv_format_t *formatlist; // optional format list for exporter
void (*shutdown)(void);
int (*resources_init)(void);
int (*cmdline_options_init)(void);
** Tested: Mac+Cocoa, Mac+Gtk, Mac+Xaw
** Open: Adapted all UIs to use generic formatlist from extended gfxoutput_drv interface


* soundrework.
'''TODO''': Decide if we want to add this to the other ports, to be included in VICE 3.2, the last release with the 'old' ports.
** oversampling setting removed. Oversampling is a bad, mostly unused solution for slightly improved audio quality. We can just do proper resamplers for machines that need it.
** shorter sound buffer requires using audio buffers to their capacity. Some drivers may exhibit bugs with bufferspace() hook when audio buffer gets completely filled. These should be identified by bad behaviour on low latency setting such as 50 ms, while other sound drivers on same system might still work.


* Userport Joystick Interface support (r20807)
==3.0==
** NEW: 2 new virtual joysticks
** API: joystick_port_map[] (arch/*/joy.[ch]) size changed from 2 to 4 (JOYSTICK_NUM, joystick.h)
** Resource: ExtraJoy (toggle) and ExtraJoyType see src/joystick.h for the types.
** TODO: UI items for the following ports: os2
** TODO: Make the joystick UI correct, to clarify: c128, c64, c64dtv, cbm5x0 and plus4 have 2 native joystick port, vic20 has only 1 native joystick port and pet and cbm6x0/7x0 have no native joystick ports at all. The HIT userport joystick adapter can only be used on c64/c128, the other userport joystick adapters can be used on c64, c128, c64dtv, cbm6x0/7x0, pet and vic20.
** TODO: Joystick mapping/handling fixes (if needed) for the following ports: gp2x.
** NOTE: Snapshots don't load/save the two new values to maintain compatibility. Network code uses the new size; this may be a problem.


* C128 RAM banks 2 & 3 support (20974)
* Added support for G71 (double sided G64 for 1571) images
** Resource: C128FullBanks (toggle)
:'''TODO''': add g71 to filters in file-open/attach dialogs in following ports: amiga, dos, osx, win32
** TODO: x128 UI items for the following ports: osx
:'''TODO''': add g71 to "create image" dialogs (DISK_IMAGE_TYPE_G71) in following ports: amiga, beos, dos, osx, win32


* Plus4 SID cart add-ons support (20977)
===r32815===
** Resource: DIGIBOOSTER (toggle) for the digibooster add-on and SIDCartJoy (toggle) for the joystick port on the sidcart.
** TODO: xplus4 UI items for the following ports: os/2, osx


* C64/C128 SFX sound sampler support (20984)
* Added support for the StarDOS drive ROM, new resources DriveXStarDos (boolean), DriveStarDosName (string)
** Resource: SFXSoundSampler (toggle).
:'''TODO''': add GUI items to the following ports (take supercard or profdos as example): amiga, beos, dos, osx, win32
** TODO: x64/x128 UI items for the following ports: osx


* C64/C128 SFX sound expander support (20993)
** Resource: SFXSoundExpander (toggle).
** TODO: x64/x128 UI items for the following ports: osx


* C128 stereo sid $d700-$d7ff range support (21007)
===r33343===
** TODO: x128 UI items for the following ports: osx


* Lightpen/gun support (21132)
* Changed a few malloc()/free() calls to lib_malloc()/lib_free(), which includes some code I cannot check (OSX for example), so should you run into errors/warnings when running VICE with -debug enabled, let me know. I think I got it right, but you never know.
** NEW: Lightpen/gun emulation in x64, x128 and xvic
** Resource: Lightpen (toggle)
** Resource: LightpenType (enum, see lightpen.h)
*** 0=Pen with button Up (TODO: product name?)

** TODO: Lightpen driver and UI items for the following ports: amiga, beos, os/2
** NOTE: see SDL or win32 for driver implementation example

** NOTE: CartridgeFile and GenericCartridgeFileX000 and NOT meant to be manipulated directly by the UI. See the above note.
** TODO: .crt like cartridge format (.vrt)
** TODO: UI items for the following ports: os/2, osx


* Fragment size (21388)
Here is a short overview of all branches that are currently active in SVN, i.e. someone develops a new feature that soon will be merged into trunk. Note here the upcoming features, if some testing is required on specific platforms or there is something porters need to be aware of. When a branch was merged into trunk, the respective info should be moved to the [[Developer_log_old]] Page.
** NEW: fragment size is switchable (with archdep defaults)
** Resource: SoundFragmentSize (enum, see sound.h)
** TODO: UI items for the following ports: osx
** TODO: check if archdep defaults are sane


* Opposite joystick directions (21417)
* 2.3-new-cpu-cores (blacky)
** NEW: Opposite joystick directions can be enabled
** This branch is all about (old and) new cpu cores, it is meant to implement the following:

*** <strike>65802/65816 support as used in some accelerator carts, but also as direct 6502/6510 replacement (65802 only).</strike> (core is in the trunk and used by xscpu64 as the main cpu core).
*** <strike>6809/6309 support as used in the super pet.</strike> (core is in the trunk and used by the superpet)
*** 8088 support as used in a copro board for the cbm2 (able to run cp/m-86 and msdos 1.25).


* Hummer userport cleanup (r21444)
* driveupdate (soci)
** Resource: HummerUserportDevice removed
** The point is to have a single FDD emulation for all drives which need low level media emulation and caching. The disk image handling is also reworked to make simpler to use and extend it later. Some features were added like handling of d71 double sided emulation mode disk images, real 6502 FDC with GCR image (works for 1001 now, planned for others). Improved fault handling and updating of Dxx images, 1581 and other MFM drives needs some work. Planned is to get the 1571 MFM mode somehow working together with the GCR mode (probably not on the same type of image file), and maybe implement G64 image support for the IEEE drives. And of course all these changes brings some new bugs to fix. This is most likely not going to be finished in 2011, and maybe some parts should be migrated to trunk to get some of the ready stuff out earlier.
** Resource: HummerUserportJoyPort removed

** Future: device number comes from the image instead of VICE.
** Future: vdrive support. Good luck ;)

Latest revision as of 19:26, 23 March 2023

As of the 3.2 release, this page is no more used. All developers are supposed to update the GTK3 and SDL ports when they add things that need GUI items.


The developer log is intended to be a central place for all developers to take down notes on what has changed during development. This helps to keep all porters up to date regarding API and Resource changes.

Trunk

Here is a short overview of all changes made in trunk that are relevant for the respective port/gui maintainers.

Note: new stuff should be added at the bottom and each item should have the related svn revision

To keep the size of this list down (and hopefully shrinking) ...

  • Port/GUI Maintainers should remove their port from the respective item when it is implemented.
  • To not clutter this page with stuff that will not get implemented anytime soon ("i will not add lightpen support to this handheld port") in such cases the respective port should also get removed from the respective item, and a note pointing out the missing feature should get added to Todo#Ports_.2F_UIs instead.
  • Items which have no more TODOs left should then be moved to the Developer_log_old Page

r34242

  • added tapecart emulation, still needs GUI hookups

Tapecart support has been added in the Gtk3 UI and the SDL UI, including a 'flush image button' which uses the new tapecart_flush_tcrt() function in tapecart.c.

TODO: Decide if we want to add this to the other ports, to be included in VICE 3.2, the last release with the 'old' ports.

3.0

  • Added support for G71 (double sided G64 for 1571) images
TODO: add g71 to filters in file-open/attach dialogs in following ports: amiga, dos, osx, win32
TODO: add g71 to "create image" dialogs (DISK_IMAGE_TYPE_G71) in following ports: amiga, beos, dos, osx, win32

r32815

  • Added support for the StarDOS drive ROM, new resources DriveXStarDos (boolean), DriveStarDosName (string)
TODO: add GUI items to the following ports (take supercard or profdos as example): amiga, beos, dos, osx, win32


r33343

  • Changed a few malloc()/free() calls to lib_malloc()/lib_free(), which includes some code I cannot check (OSX for example), so should you run into errors/warnings when running VICE with -debug enabled, let me know. I think I got it right, but you never know.

Branches

Here is a short overview of all branches that are currently active in SVN, i.e. someone develops a new feature that soon will be merged into trunk. Note here the upcoming features, if some testing is required on specific platforms or there is something porters need to be aware of. When a branch was merged into trunk, the respective info should be moved to the Developer_log_old Page.

  • 2.3-new-cpu-cores (blacky)
    • This branch is all about (old and) new cpu cores, it is meant to implement the following:
      • z80 support for x64/x64sc (z80 cp/m cartridge). (code is in the trunk and used by the c64 cpm cart)
      • 65(S)C02 support as used in some accelerator carts, but also as direct 6502/6510 replacement. (core is in the trunk and used by the fd2000/4000 drives)
      • 65CE02 support as direct 6502/6510 replacement.
      • 65802/65816 support as used in some accelerator carts, but also as direct 6502/6510 replacement (65802 only). (core is in the trunk and used by xscpu64 as the main cpu core).
      • 6809/6309 support as used in the super pet. (core is in the trunk and used by the superpet)
      • 8088 support as used in a copro board for the cbm2 (able to run cp/m-86 and msdos 1.25).
  • driveupdate (soci)
    • The point is to have a single FDD emulation for all drives which need low level media emulation and caching. The disk image handling is also reworked to make simpler to use and extend it later. Some features were added like handling of d71 double sided emulation mode disk images, real 6502 FDC with GCR image (works for 1001 now, planned for others). Improved fault handling and updating of Dxx images, 1581 and other MFM drives needs some work. Planned is to get the 1571 MFM mode somehow working together with the GCR mode (probably not on the same type of image file), and maybe implement G64 image support for the IEEE drives. And of course all these changes brings some new bugs to fix. This is most likely not going to be finished in 2011, and maybe some parts should be migrated to trunk to get some of the ready stuff out earlier.
  • vice-1990 (soci)
    • Branch for emulating the 1990 drive.
    • TODO: user interface for Drive?Swap8Button, DrivexSwap?Button, Drive?WriteProtectButton
    • TODO: gui changes so that this type can be selected
    • TODO: RTC72421 emulation needed (in trunk)
    • TODO: proper disk image attaching, hdd/iso/fdd image types? Currently file is hardcoded to "/tmp/image" for all!
    • Future: geos, swap8, swap9 and write protect LEDs on GUI would be nice
    • Future: device number comes from the image instead of VICE.
    • Future: vdrive support. Good luck ;)
