Re: Trying to find dosbox 0.63.

It needs 64Mb of memory. Then the intro crash will go away. That should get you started, TomCat39.

Okay, but until DOSBox is fixed, shall I post a binary that will work (including patching int 2e in a way that they like, etc)?

So if you build and run my code from the other thread, then you should be able to run the game without any modification. Or can I build the code and post the binary? It is permitted?

Ah, I knew that the $$$steal.me file was the problem, but I didn't have time to find out exactly why. :-( Being zero bytes long, "xcopy" won't copy it by default, and since it was hidden, "copy" won't see it either. So, you either change the attributes to ensure that it's copied, or you don't copy …
int 08 in pmode despite IF clear
Posted on 2008-07-18, 00:46
I see this problem in Circuit S3 demo by Analogue: it clears interrupts, it enters protected mode, it executes rep movsb. Before the mov finishes, an int 08 occurs, which is serviced. This causes flags/cs/eip to be placed on the stack which overwrites (due to poor coding by Simm) the previous return …
Re: multiple GUS register selection

I suppose that's how they work. The demo polls for an acknowledgement, and works nicely (with sound) if I bypass that. I will make a patch for the demo.
multiple GUS register selection
Posted on 2008-07-09, 15:00
Triangle demo by Trillian crashes during GUS init. I see this code: outb 0x343, 0x42 outb 0x344, 4 sets low 8 bits of gRegData, waiting for second byte outb 0x343, 0x41 outb 0x345, 0x81 sets high 8 bits of gRegData, then issues the command to assign register 0x41 only. Two problems: low 8 bits are …
Re: Emulation inside emulation: DOS-based emulators under DOSBox.
Posted on 2008-07-04, 14:40
Neither of them could play Randamn when I tried, though (~2004). Randamn had lots of cool tricks, like z-page wraparound, and instruction timings. To play it, I ended up running an Apple emulator inside an Amiga emulator, under Windows. I didn't know about DOSBox at the time. That would have been an …

If you must use the cracked version (though you should find an original), then you'll need my patch (which I can't post here). The Prestige crack is bad and doesn't work in DOSBox.
Re: Vista help with DOSBox

The disk space might be exactly the problem, but because it's too large - for really large disks, there can be an integer overflow in DOS while calculating the free space. The result is a small number from the game's point of view.
Re: Installing Toonstruck
Posted on 2008-06-17, 22:20
run setup.exe, it copies lots of files, and creates a toonstrk.bat. that's the game launcher. it works fine for me. maybe your copy is bad. try the original cds.
Re: Toonstruck help please
Posted on 2008-06-17, 22:17
reactivate this, just to answer it properly: the problem is not the sound settings, it's the CPU speed. set the cycles= to something small, maybe 30k or less.

one of the best Apple II-only games was Captain Goodnight, if you like action games. Also Short Circuit, Black Magic, Randamn, Crisis Mountain, the original Lode Runner, Choplifter, Airheart, ... Some others exist on other platforms, but the ports are poor, so I still think of them as Apple II-only …

Re: SaveRegisters() not used for general int 21h calls
Posted on 2008-06-02, 14:44
I've seen a couple of examples recently. One is the Babes demo by The Coexistence. I don't remember the other name because it was a really bad demo so I assumed the problem was in the demo and not DOSBox. :-) It's rare but it happens. The register order doesn't match DOS (should be abcdx not acdbx), …
SaveRegisters() not used for general int 21h calls
Posted on 2008-06-01, 22:56
This is a problem for anything that executes files manually (ie alloc mem, read file, duplicate PSP, hook int 22, run the code). The problem is that after the execution of int 22 to resume from the parent, the registers are all destroyed. Real DOS saves the registers on all calls to int 21h. I …
Re: DSP_Reset() does not clear sb.dsp.out.used

anyway, there's a patch for Mental Surgery on my site, so now it works even with the broken method.
Re: DSP_Reset() does not clear sb.dsp.out.used
Posted on 2008-05-31, 19:46
it reads 0x22e until the value is 0x7f (ie no data available), then it reads from 0x22a to check for the 0xaa. So real hardware does pulse the bit. DOSBox would need a timer of some kind to emulate that properly. It's probably easier to just patch the individual apps instead.
Re: DSP_Reset() does not clear sb.dsp.out.used
Posted on 2008-05-28, 20:55
okay, but there is no mention of what happens during the delay. What happens if you keep waiting? Or don't wait long enough? Perhaps it's just a pulse? STMIK reads the port up to 1000 times waiting for the bit to clear. Since that code did work on real hardware, it makes me think that the bit goes …
