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

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

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

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

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

• • 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.
  • TODO: fix gui items in following ports: osx

• NEW: Atari ST mouse and the Atari CX-22 trackball and improved Amiga mouse emulation by Magnus Lind.
  • TODO: Check and test UI items for Atari ST mouse and Atari CX-22 trackball (osx)
    • testprograms can be found in testprogs/propmouse

2.3.10 (r24627)

• Added 3rd sid support for x64 and x128 (r24733).
  • changed Resource: "SidStereo", instead of 0=off, 1=on, it's now: 0=off, 1=1 extra sid, 2=2 extra sids.
  • new Resource: "SidTripleAddressStart", the address of the 3rd sid.
  • TODO: add/change gui items in the following ports: osx

2.3.15 (r25340)

• added support for "Formel 64" parallel cable (r25438)
  • extended resources Drive8ParallelCable, Drive9ParallelCable, Drive10ParallelCable, Drive11ParallelCable (enum) from 0..2 to 0..3 (DRIVE_PC_NONE, DRIVE_PC_STANDARD, DRIVE_PC_DD3, DRIVE_PC_FORMEL64). added DRIVE_PC_NUM respectively (drive.h)
  • TODO: update gui items in following ports: os/2

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.

2.3.21 (r26032)

• added "SuperCard+" emulation (this is a drive expansion board for 1541/1570/1571/1571cr)
• 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: os/2, osx

2.3.22 (r26155)

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

---

2.4

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

r27046

• NEW: Resource "DriveSoundEmulationVolume" (integer, 0 - 4000) to adjust the volume of the drive noise emulation

  • TODO: add GUI item(s) in following ports: os/2

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: os/2
  • 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.
• 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: os/2

TODO: Update/Fix GUI items in following ports: amiga, beos, dos, os/2, osx

r29938

• added new joyport system. The new system makes things modular. On one side you have the devices that can be on a joyport, and all the code for those has to do is handle reading/writing of digital lines and reading of the pot-lines. On the other side you have the 'chip' emulations that deal with the hardware emulation. The new system handles the traffic between the two sides, handles conflicts between input resources that devices use and provides a way for the gui's to query what devices are present (name and id).
• new resources related to the new joyport system: "JoyPort1Device" (int), "JoyPort2Device" (int), "JoyPort3Device" (int) and "JoyPort4Device" (int)

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
  • 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 ;)
