I don't know if people on this place are interested in something like this, but I might just as well post it here just in case. I've written a program which creates sounds that are, imo, pretty un-Gameboyish. It tries to emulate a resonant filter of sorts. Even if you're not into making music with G...

I had a look at the patch. So, the patch is removing the code which calculates a value to be written as the upper nibble of the value that is being written to $7000. The lower nibble apparently limits the ROM size that's visible to the program, whereas the upper nibble is probably meant to limit the...

Fail! You seem to be doing everything you can to make sure the game doesn't run on real hardware. Invalid header values and invalid VRAM accesses. Use BGB for debugging instead... And why the "complicated" controls? Why not just make A start the trail, and automatic win condition if all ti...

I can't imagine why they didn't give the "master registers" a protection control so that once a game is launched the game can't effectively kill itself. That would have killed the feature that many of these flash cards had, at least in the GBA era, to patch a game to reset to the menu upo...

It seems like you are right. I tried this in BGB and interrupts are disabled at the start of that test, as expected. (On second thought, though, this may not be to test the DI instructions as such, but to check interrupt can be disabled at all. The DI is just there so that individual test could be r...

1) That was that version and not the latest 2) I'm getting maybe 20-30 FPS here Super Mario World. (Don't remember since the last time I turned that computer on.) Might vary depending on the game as well, of course.

I want to have it for fun. I want to try it on a P100 laptop I have. no$sns Win performance is worse than ZSNES DOS performance, and even that is almost useless on that computer. But maybe Martin's asm+DOS can do wonders for this machine. On the other hand, ZSNES is written in asm, too...

I've donated to get access to v 1.2. I'm noticing that assigning buttons on an external game controller now works. However, the default values created a confusing problem for me. I have a SNES controller adapter with two ports. For whatever reason, I had the controller plugged into port 2. After ass...

tepples: Aha! I never actually looked into how the NES's DPCM worked and I didn't realize that 1) it has controllable frequency 2) it can be loaded with an arbitrary sample. That does indeed invalidate this us for the triangle channel completely. (Not that it was very viable to begin with.)

Just a crazy idea how the increased triangle control could be used: You could use it for what I would call "sparse sample playback". The new resgister would allow you to control the phase position, as well the frequency (as usual). The way this could to your advantage is by successively ap...

I know nothing about 65816 programming, but looking at the opcode chart, this instruction seems to be incorrect, and I would maybe blame the assembler. 0000:BF8B A9 CC 8D lda #8DCC lda with an immediate argument should have a two byte argument (right?). Your assembler turns "lda #0CCh" int...

Gilligan, you should be able to load symbols by creating a file which has the same file name as the ROM, but with extension sym instead of sfc, smc, bin or whatever. The format should be something like: 0000:0000 something Where the first two digits are the bank or whatever (or 0 if not applicable) ...

So have I. Now it will be interesting to see if byuu will approve my post. That is a rather insulting insinuation :P Backgound: I registered a year ago and was almost sure I posted something back then. Approving the first post makes sense, but if you need manual approval for more than one post, you...

Which service pack? I think support .hlp files was removed in SP3 or so for vague security reasons.

Another thing. The help files that are created by no$*** are incompatible with modern versions of Windows (XP with later service packs and later.) There are third party software that can read the files to some degree, but I would suggest distributing help files as HTML files. Maybe it's anti nocash ...
