I tried to specify full path to right libgcc.a, does not help. Strange thing, if I remove both math code from sega.s and reference to libgcc.a from makefile.gen (and even delete libgcc.a file), nothing changes - project compiles successfully and works with same problems. That's definitly not normal...

It's an issue with all compilers. They expect the values to be initialized before calling main(). It's all in how you set up the linkage. For a binary that loads into an operating system, you want the initialized segment to load right into memory along with the code. For ROM code, you need two thin...

I realised i never replied your last post. I think the 32 bits modulo operation is buggy, i guess you're doing it on 32 bits sized variable ? I rarely use modulo but i never meet any problem with division. I'll check the 32 bits modulo code in sega.s file, maybe a stupid bug. I did some tests today...

I'm a bit septic ot maybe i doesn't understand what you mean. You said the frequency cycle is ~20Khz, i always though it was ~55 Khz. If it's really 22 Khz then a record at 96 Khz would be revelant about the multiplexed sample. If only the DAC is active then we should obtain something like that (96...

I will try to explain some HW "features" of YM2612. As I told, I done some research work with analog part of YM2612 on one russian forum (wich is already dead). You can do this to, using a good oscillograph. YM2612 using time-multiplexed channel mixing. It use 6 "slots" on every cycle. It looks lik...

Agreed =)
FM synthesis is cleverely explained and sounds less obscure for me now.

I love how accurate emulators are, I tested five of them and there was no match between them in the output at all o_O So bad I can't test on the real hardware, but I would want to see a more zoomed version of the samples, I want to make sure it isn't just that the program skips the samples between ...

Well, i just completed my new Z80 driver. As the Shiru's driver it's a 4 PCM channels players, the only but major difference is that it can play 8 bits PCM sample as the driver does saturation if needed. Initially i wanted a stable 16 Khz playback and to be sure to get on the hardware i used pessimi...

If the bank switch would be one (or 2) write(s), then it would be all easy... no need for memory buffers and such... my implementation wouldn't be too accurate for speed reasons but would be enough for drums, which is what I need samples for. Yep that bank register which work "bit per bit" is a pai...

-Sonic 2's two player mode flickers, as where Gens and Kega don't. I didn't check 0.85 yet, but as far as I know, the real hardware does flicker, showing even lines in one frame and odd lines in the next. Fusion and Gens don't emulate that properly, and it annoys me honestly. -1:1 pixel in interlac...

There's one emulator called ApprenticeMinusDS that is a SMS/GG Emulator, runs at 60FPS clean, and like you said the resolution matches it is simply beautiful. I played Phantasy Star and SRAM works great too. There's also an emulator called jENESIS that runs most games I tried, and all at 60 FPS, wi...

OK, I've been thinking about a Genny emulator for the GBA for an hour, turned enthusiastic, really, indeed, and felt in front of this answer from MoD : you can't guess what's code and what's data ... :( Oh my ! C U Genny fans. I had the same idea a long time ago. I was thinking about dynarec tech b...

Already saw that. And 10FPS (you) vs. 30FPS (me) *shot* Through seriously, it would be interesting to see how well does my subroutine perform in the real hardware (I can't test that). Also, I could make this subroutine even a bit faster (specially when you adapt it to a specific size), but I'm not ...

Here is a DEMO for test Gen emulator DAC stuffes.The musc was got from Top Gear2 SFC edition.This demo not tested on real hardware yet.
