Huh?

He means that this is one of the only games/emulators entered into the homebrew competition so far.


The only other games/emus are DS(i)x86 and Mind Maze, the rest are coding-related or menus/loaders.

Version 0.05 released!

The major improvements and fixes in this version are the following:

- Preliminary support for high resolution EGA/VGA modes 640x200, 640x350 and 640x480 added. NOTE! Scaling does not work properly in these modes yet.
- Implemented preliminary support for Mode-X mode 360x240 (for the Settlers game).
- Implemented a lot of missing opcode variations, now a majority of the most common opcodes have been implemented, but many rare opcodes are still missing.
- Increased the EMS memory size to 4MB, which allows Elder Scrolls: Arena to start up.
- You can now switch between the configuration sections in the INI file on-the-fly, by clicking on the current configuration name.
- Fixed a stack alignment problem in overlay loading, which caused an "Exception 5" error in some programs.
- Fixed a bug in SETZ opcode, which caused Warcraft to hang when giving a command to dig gold. NOTE! It is recommended that you play Warcraft with "no sound", as the SoundBlaster emulation in DS2x86 seems to cause intermittent freezes and crashes.
- Fixed a bug in division-by-zero interrupt handling, which caused Formula One: Grand Prix to fail.

Please send me the debug logs from this version again, they are very helpful when I improve DS2x86!

Does it run QBASIC or at least GWBASIC/BASICA? That would be pretty interesting and a reason to run out and buy a DS Two.

Good luck with the contest.

Good luck with the contest.

I havent tried it myself, but by looking at the compatibility wiki, QuickBASIC (QBASIC predecessor) runs on the regular DSx86.

QUOTEQuickBasic 4.5
Playable
Works perfectly, though it won't switch to screen modes 11, 12, or 13. Sometimes it gives "unsupported INT call" error when doing a for loop

Version 0.06 released last Sunday! It does not have any major new features, just small fixes and improved protected mode opcode support.

hi,

A little question about "warcraft" (on DS2X86 v0.06), when you select at the main menu "start new game" than "single player" and than "custom game" when selecting a worker to build the "farm" the button is missing. Also when selecting "town hall" the fallowing builds are missing: "build road" and "build wall".

has any one else the same issue ?


Edit:
Solution; make a save in dosbox and load the save file whit DS2x86.

Version 0.07 released!

This version has the following improvements:

- Blinking cursor in text modes (finally!).
- HIMEM.SYS emulation added, allows Chaos Engine to run.
- Fixed a serious total crash problem in 32-bit string opcodes.
- Fixed a stack alignment problem that could cause "Exception 4" BSOD errors.
- Improved BSOD reporting, now includes a stack trace.
- Improved horizontal blank reporting, this might solve hanging problems in some games.
- Improved Mode-X graphics blitting code to handle wrap-around properly.
- Changed the screen refresh interrupt interval from 60Hz to 59Hz. This might help with the intermittent "stuck key" problem in some games.
- Direct file read to EGA memory is now supported (f.ex. in "Heimdall").
- Implemented a number of previously missing opcodes.

Complete list of games tested

Don't expect sound for a while since that part has not been fully coded into DS2x86 yet. Nothing like what is coded into DSx86. Although I hope Pate is able to code that portion soon. Most games just aren't the same without it.

 

[Pate]

I plan to add proper audio support into DS2x86 during my summer vacation (in July), if I don't have time to do it sooner. I would like to start working on it already, but there are still so many hanging and crashing issues with the CPU emulation that I think I'll need to make that more robust before working on the audio side.

[Buleste]

Many thanks for your hard work as always.


EDIT:SOUND!!!!! We have sound on some games (albeit not high quality but this is due to the crappy SDK rather than Pate's excellent hard work).
DUNE2 now has sound.
UFO - Enemy Unknown and X-COM - Terror From The Deep can run the intro movie with sound but you cannot play the game yet.
Frontier - No sound
Bloodnet - No sound and running the setup and selecting Soundblaster causes crashes.
Knights of Legend - No sound (but then it doesn't support SB anyway).

Time to test a few more.

EDIT2: I've tested some more games and whilst I have not found anymore working games with sound I have found the following
Syndicate - Intro runs with sound (game still not working).
Dungeon Master 2 - The Setup test of the sound card works and plays the test. It also auto detects the sondcard (game still not running).
X-Wing - Initialises the sound (you hear a click) but doesn't actually play any

@Mad008 Settlers is now working fine.

 

[Pate]

Version 0.09 released!

This version has the following improvements:
- Implemented screen scaling for all common graphics modes.
- Fixed the DOS and BIOS date/time functions to return proper Real Time Clock values. This might fix some hanging games.
- Fixed EGA Read Mode 1 handling (fixes EGATrek graphical issues)
- Fixed EGA Read Mask initial value (fixes Ultima V hanging)
- Added a warning message for games that need a Floating Point Unit.
- Screen copies are saved to incrementally numbered files SCR00.BMP..SCR99.BMP.
