Re: rpix86 (Raspberry Pi x86 emulator) version 0.10 released

@joacliba: Thanks for the log! Looks like the game tries to use the old (DOS 1.0) FCB file commands to create a file (http://www.ctyme.com/intr/rb-2581.htm). I haven't supported that command in rpix86 yet, I'll see how much work adding that would be. @forenbenutzer: I will probably need to test that...

Re: rpix86 (Raspberry Pi x86 emulator) version 0.10 released

If you are on Windows, you will probably need to have some utility program (WinZip, 7-Zip, WinRAR), which you can use to browse inside the 4DOS750.EXE and extract only the 4DOS.COM. Perhaps in Linux you could simply use the unzip program? The directory you mention seems to be correct. I have to say ...

Re: rpix86 (Raspberry Pi x86 emulator) version 0.10 released

You can try finding 4DOS from some mirror site. I googled for such, and this seems to be one alternative: ftp://ftp.mathematik.uni-marburg.de/pub/mirror/jpsoft/oldver Get the 4DOS750.EXE, do not run it but unzip it (it is an executable zip file), and get the 4DOS.COM from there. I'm sure there are o...

Re: rpix86 (Raspberry Pi x86 emulator) version 0.10 released

Thanks for the detailed bug report again, Vanfanel! Based on the crash log it looks like Dungeon Master II attempts to enable paging (virtual memory), so it crashes because that support is not implemented. This is a lot of work to implement and would most likely slow everything down considerably, so...

Re: rpix86 (Raspberry Pi x86 emulator) version 0.09 released

I do not dare to ask: Any progress with the second serial port? :) Thanks for the reminder! I'll try to get this implemented into the next version. I'll need to move the internal mouse emulation out of the way (as it currently uses the COM2 port IRQ3), so this may cause changes to the mouse behavio...

Re: rpix86 (Raspberry Pi x86 emulator) version 0.09 released

Thanks for testing the games! Sorry I've been busy with other things besides rpix86 for the past week, so have not made any progress with the problem games yet. I do plan to continue working on it in the near future, though. :)

@Vanfanel, glad to hear my fixes to Alone in the Dark worked. :) I'll take a look at those other games you mentioned, and fix their behaviour if possible.

@Jessie: Thanks for the compliments. :)

Re: rpix86 (Raspberry Pi x86 emulator) version 0.08 released

@Lexusjjss: I have been debugging the audio problems in Star Control 2, and fixing that is quite difficult. It uses Direct DAC SB audio, meaning that it sets the PC timer to run at 8400Hz and outputs one sample of audio at every timer interrupt. My current architecture emulates the timer interrupt u...

Re: rpix86 (Raspberry Pi x86 emulator) version 0.07 released

Ok, thanks for the extra info! I'll take a look at those games. I actually tested NHL '94 yesterday, strange that I could not make it run even without sound until I made a couple of small fixes to rpix86. I did find the black screen problem (it actually drops back to DOS), but haven't yet debugged t...

Thanks for the encouragement emuola! :) Which games have you tested, where the SB does not seem to work? I'm sure I have many problems still remaining in my SB emulation, but it would help to have specific problematic games to test. I will see about supporting NHL '94, I believe it should run in rpi...

Re: rpix86 (Raspberry Pi x86 emulator) version 0.07 released

Great news. Is there a pissibility for a second COM port emulation? Sorry for the delayed reply! Yes, I think this would be possible. Currently some of the code is somewhat hard-coded to support only a single serial port, and I also have the other serial port address used by the mouse emulation, bu...

Re: rpix86 (Raspberry Pi x86 emulator) version 0.07 released

Ok, thanks for the info about the OPL music causing the slowdowns in Alone in the Dark. I have noticed that it runs slower than it should, but didn't get even that far in my debugging the cause. Probably it is indeed some timing issue, perhaps the game uses the AdLib timers (which are very poorly em...

Re: rpix86 (Raspberry Pi x86 emulator) version 0.07 released

Hi Vanfanel! I tried a couple of changes to my VSync handling to improve the scrolling in Keen1, but both of the changes, while improving that game slightly, made some other games scroll really bad. So, I have not yet found a technique that would make all games behave nicely. I'll continue looking i...

Wow, much appreciated benrett! Looks like you spent quite some time writing that tutorial, great work!

I trust you don't mind if I link to your tutorial from my rpix86 pages? I plan to update my pages this Sunday, so if I forget to link to your tutorial at that time please remind me!

Re: rpix86 (Raspberry Pi x86 emulator) version 0.06 released

Ok, I'll do that. Or perhaps I could just remove my version and instead point to that proper Atari800 cvs location. There is no need for me to host the same source file separately any longer, I think.

Re: rpix86 (Raspberry Pi x86 emulator) version 0.06 released

Thanks for the error logs! Those should help me figuring out the problems. Jazz Jackrabbit uses virtual memory, so it will not run in rpix86, sorry. For VSync emulation I use the hardware VSync, so the games will run with a 60Hz VSync even when they think they run at 70Hz. This may make some games r...

Hi Vanfanel, thanks for testing rpix86 further! - The scrolling problem in Commander Keen 1 is probably caused by the way it syncs to the VGA vertical refresh signal. It is pretty tricky to get the emulated vsync to work as expected in all games. I have been using Supaplex and Commander Keen 4 to te...
