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

---

2.2.7 (r22889)

• NEW: archdep_fix_permissions (r23053)
  • should set the permissions of a given file to "rw", respecting the current umask (if any)
  • TODO: add proper code for the following ports: beos
  • TODO: ...and copy to arch/sdl/archdep_* when doing that

---

2.3.9 (r24210)

• additional functions signals_pipe_set() and signals_pipe_unset() added in arch/*/signals.c (r24261)
  • to check if a port needs this implemented, type this into one terminal:

  x64 -remotemonitor

  and this into another:

  echo "reset" | nc -p 6510

  now terminate the connection by pressing ctrl-c. if the emulator now quits (or crashes) you probably need to handle SIGPIPE, ie set up a signal handler for SIGPIPE that calls monitor_abort() (see the unix code as an example). if not, just locate the respective fixme note in 'your' sourcefile and remove it.

  • TODO: check/confirm/implement for the following ports: amiga, beos, dos, os/2
  • TODO: ...and copy to arch/sdl/archdep_* when sigpipe handling is required

• added model selection to xplus4 (r24285)
  • look at plus4/plus4model.h for models and functions, it works just like the c64 counterpart
  • TODO: add GUI items to following ports: osx

• xplus4 cartridge system unified to common api (r24285)
  • new Resource: CartridgeReset (BOOL, default = TRUE)

    when enabled, reset the emulated machine when changing cartridges

  • TODO: add GUI items to following ports: osx

• added model selection to x64dtv (r24287)
  • look at c64dtv/c64dtvmodel.h for models and functions, it works just like the c64 counterpart
  • TODO: add GUI items to following ports: osx

• video_render_initraw() takes additional render config parameter (r24308)

• after above changes, check wether VDC and VIC-II palettes can coexist, and update the todo list here: Todo#Ports_.2F_UIs
  • TODO: check following ports: beos, osx

• put the status of the vsid ui into the todo list here: Todo#Ports_.2F_UIs
  • TODO: check following ports: beos, dos, osx

• xcbm5x0 splitted from xcbm2 into a seperate machine and binary (r24326)
  • Resource "UseVicII" removed (no more needed)
  • due to the split, some features are no more available/needed in one or the other:

    cbm5x0:

    • remove "crtc settings"
    • remove all _but_ "510" from model selection
    • remove basic128/basic256 ROM related options from ROM settings, load "rom500.vrs" as standard roms option instead
    • remove "7x0 (50 Hz)" from modelline selection
    • add 64kb as memsize option

    cbm2:

    • remove "vic-ii settings"
    • remove "vic-ii model" from model settings
    • remove "510" from model selection
  • TODO: fix gui items of following ports: beos

  • look at cbm2/cbm2model.h for models and functions, it works just like the c64 counterpart
  • TODO: add/fix GUI items to following ports: beos, osx

    ... and remove cbm2_get_model() if done so

    • TODO: remove usage of cbm2_set_model() in following ports: beos

    ... and make cbm2_set_model() static (use only for cmdline)

• xcbm2/cbm5x0 cartridge system unified to common api (r24326)
  • new Resource: CartridgeReset (BOOL, default = TRUE)

    when enabled, reset the emulated machine when changing cartridges

  • TODO: add GUI items to following ports: beos, osx

• • cartridge_attach_image(type,name) and cartridge_detach_image(type) are now available in xcbm2/cbm5x0, look for types in cartridge.h
  • direct usage of "Cart1Name", "Cart2Name", "Cart3Name", "Cart4Name" resources is deprecated, use the above functions instead.

• Fixed the sound system to handle mono and stereo streams correctly (r24693).
• Output is selectable between 'system' (system decides to use mono or stereo output based on the presence of a stereo sid), 'always mono' (output is always mono, stereo streams are mixed into a mono stream) or 'always stereo' (output is always stereo, mono streams are multiplexed to a stereo stream).

r25459

by Rhialto

I enabled up to DRIVE_NUM IEEE-488 drives, rather than 2 (in True Drive Emulation mode). In some places where they are enumerated, it is 4. The drives use their full 3 bits of jumpered drive number now, rather than just 1 bit.

I have also generalised code so as to allow another dual drive. Since dual drives currently use up two device numbers, it will use 10 and 11. I'm currently simplifying the methods for checking the dualness of a drive.

When that is done, I hope to have gained enough understanding of the code to remove the horrible hack of using 2 devices for a dual drive, and remove it. It looks like it will simplify a lot of code (including removing lots of code that I changed for allowing 2 dual drives). That will have some repercussions on the GUIs, since for every drive you may need to be able to attach two image files. It also would add an extra "drive" parameter (in addition to the current "unit" parameter) to a shedload of functions, although this is a pretty mechanical change. In fact, it is the GUI change that currently holds me back...

TODO: Think of some elegant way to represent settings for 8 floppy images (for 4 dual drives), without requiring all GUIs to be updated at once. TODO: After that, I can rework the code to make dual drives more regular and hence allow 4 of them.

2.3.19 (r25940)

• removed unused "Romset<NAME>" resources
• TODO: fix win32 port (./arch/win32/uirom.c, find "Romset%s" - the "Computer resources saved to romset" and "Drive resources saved to romset" dialogs and the buttons opening them can be removed, they never worked :))

2.3.21 (r26032)

• added "SuperCard+" emulation (this is a drive expansion board for 1541/1571)
• new Resource: "DriveSuperCardName" (string) that specifies the SuperCard ROM image
• new Resources: "Drive8SuperCard", "Drive9SuperCard", "Drive10SuperCard", "Drive11SuperCard" (toggle) that specify whether SuperCard is enabled for the respective drive
• TODO: add GUI items to following ports: amiga, beos, dos, os/2, osx, win32

2.3.22 (r26155)

• added Smart mouse emulation
  • TODO: check if GUI items work on following ports: beos, osx

• added c64/c128/vic20 DS12C887 RTC expansion emulation
  • new Resource: "DS12C887RTC" (BOOL) DS12C887 RTC cart on/off
  • new Resource: "DS12C887RTCbase" (int) DS12C887 RTC cart base address
  • TODO: Add GUI items to the following ports: beos, osx

• added c64/c128 RTC58321a userport RTC expansion emulation
  • new Resource: "UserportRTC" (BOOL) 58321A RTC on/off
  • TODO: Add GUI items to the following ports: beos, osx

• added c128 internal function RAM and internal function RAM+RTC support.
  • The Resource "InternalFunctionROM" now has a new meaning: 0=off, 1=ROM, 2=RAM, 3=RAM+RTC
  • TODO: Adapt GUI items for the following ports: beos, dos, osx

• added fsimage-dxx.c for concentrating d64/d71/dxx image handling.
  • TODO: check build project. The .tgt files are not updated, other uncertain.

• added general image track extension
  • TODO: Translation and related dialogs are not up to date. It's not just d64 extending to 40 tracks, but general extending of d64 and d81 images to various track numbers. One simple question like "Do you want to extend the image?" would do. (To clearify: the existing message should be made more generic)
  • TODO: check/fix GUI elements of following ports: amiga, beos, dos, os/2, win32

2.4 (r26680)

• updated the datasette emulation to also work as expected when there is no tape image present
  • all UI elements should be always visible and enabled (as with a real datasette :))
  • the parameter passed to ui_set_tape_status can then be used to somehow indicate whether a tape image is present (eg by using a different color)
  • ui_set_tape_status, ui_display_tape_motor_status, ui_display_tape_control_status and ui_display_tape_counter in ui code perhaps must be updated to handle being called before the respective gui item has been created (which unfortunately can not be avoided easily with the current architecture)
  • TODO: Check and if required adapt GUI items for the following ports: beos, dos, os/2, osx, win32

2.4.1 (r26948)

• added missing c64 models (C64MODEL_C64SX_PAL, C64MODEL_C64SX_NTSC, C64MODEL_C64_JAP, C64MODEL_C64_GS, C64MODEL_PET64_PAL, C64MODEL_PET64_NTSC, C64MODEL_ULTIMAX)
  • TODO: update GUI items in following ports: osx

r26968

• added model selection for xvic, it works just like the C64 functions (vic20model_get/vic20model_set; VIC20MODEL_VIC20_PAL, VIC20MODEL_VIC20_NTSC, VIC20MODEL_VIC21)
  • TODO: update GUI items in following ports: beos, osx

r27020

• added mouse type for koala pad (MOUSE_TYPE_KOALAPAD)
  • TODO: update GUI items in following ports: osx

r27046

• NEW: Resource "DriveSoundEmulationVolume" (integer, 0 - 4000) to adjust the volume of the drive noise emulation
  • TODO: add GUI items in following ports: amiga, beos, dos, os/2, osx, win32

r27322

• extended Resource "SoundFragmentSize", added values are SOUND_FRAGMENT_VERY_SMALL and SOUND_FRAGMENT_VERY_LARGE
  • TODO: update GUI items in following ports: osx

2.4.4 (r27450)

• NEW: added Resource "JAMAction" to select default action on CPU JAM. (int, MACHINE_JAM_ACTION_DIALOG, MACHINE_JAM_ACTION_CONTINUE, MACHINE_JAM_ACTION_MONITOR, MACHINE_JAM_ACTION_RESET, MACHINE_JAM_ACTION_HARD_RESET and MACHINE_NUM_JAM_ACTIONS respectively)
  • TODO: add GUI item(s) in following ports: amiga, beos, dos, os/2, osx, win32

also see r27981 below

r27452

• NEW: added Resource "IECReset" (1: drives reset with computer, 0: drives do only reset on powercycle/hard reset) to x64, x64sc and xscpu64 - this should go into the "model selection" dialog (as it depends on the board)
  • TODO: add GUI item(s) in following ports: amiga, beos, dos, os/2, osx, win32
  • NOTE: while adding this, check if the model switching in xscpu64 is working (it should be like in x64sc, not like in x64!)

r27549

• Resid-FP has been removed.
  • TODO: remove related GUI item(s) in following ports: osx
• To compensate for the missing SID-Type selection, GUI items (slider) should be added for the following Resources: SidResidPassband (0..90), SidResidGain (90..100), SidResidFilterBias (-5000...5000)
  • TODO: add/update GUI item(s) in following ports: amiga, beos, dos, os/2, osx, win32, sdl

r27914

• Printer 6 (Plotter) is now available, a new menu like the existing printer menus should be added which has "1520" and "RAW" in its driver selection
  • TODO: add/update GUI item(s) in following ports: amiga, beos, dos, os/2, osx, win32, sdl

2.4.6 (r27981)

• added MACHINE_JAM_ACTION_QUIT as option for JAMACTION
  • TODO: add/update GUI item(s) in following ports: amiga, beos, dos, os/2, osx, win32, sdl

r28014

• accessing device #7 on the IEC bus works (only real devices), respective selection (0: none 2: real) should get added to the menus
  • BUG: it only works if True Drive Emulation is OFF, even though this has nothing to do with drives. This needs to be fixed in TDE somehow.
  • TODO: add/update GUI item(s) in following ports: amiga, beos, dos, os/2, osx, win32

r28109

• added support for swiss kernal/chargen to x128
  • TODO: add/update GUI item(s) in following ports: osx

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).
    • 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).
    • 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.
