Yesterday I just read about TAS instruction, I read that it is good for multi CPU systems, but I didn't quite get it. what does it really do ? From that Wiki article I read that it wouldn't work on real HW. Anyway I did quite fast 2D rotation in QB using only cos/sin table and additions, no muls/div...

What do you think, can you suggest any improvements ?

More correct would be : Must write "SEGA" if the version reg returns <> 0

MDs without BIOS exist, why else I wrote the TMSS patcher

This address is read only, only on the first model of Genesis. It was a prototype and was not released. Thus, we can consider that $A14000 will always be writable. I'm not so sure about it, I'll ask Deven Gallo, he owns $h1Tload of MDs. My pirate MD1 (which fried quite some time ago) would have pro...

EDIT oki, you always write it, are you sure it won't crash on early MD ? coz that reg adress is maybe write only Yes it will crash the early MDs but that utility is for running old games on new MDs (Alex Kidd for example). I didn't make it check if newer system is used as I thought that the code ge...

Yes, sample rate gets slower. PCM playback is the best way to measure code performance because every improvement shows up in sound.

Anyway source is up, like always on my site's MD section.

Try my TMSS patcher on your ROM, I have noticed, that patched ROMs will run, but the "produced by ..." message does not appear.

Yeah, jump to PC is there, I feel like total ass.

What font do you use in the debug windows ? In the manual, windows shots look ok, but on my system, the fonts are stretched out and display incorrectly (I can provide a window shot).

I like it !!! You should make the CPU/VDP debug windows little bigger, some stuff gets hidden. Also you should add "jump to current PC" in the CPU windows. One nice feature (if it's possible) is the option to turn on/off separate YM2612 sound channels. I hope I'm not asking too much...

Any hints on what you'll release ?

I'm one of the WIN98SE users who will stick to it forever and if the software won't run on it I won't use that software anymore. If you're wondering why I like Win98SE so much, it is so because 80% of the programs I have are for MS-DOS and in my mind Win98SE is the best platform for DOS stuff (well,...

Yes, the software does it automatically with no clicks or pops 8) For larger files you can always uncomment ~10 lines in the source (makes things slightly slower) if you need to play long samples. You don't need any additional "tweaks". As for unrolling, it makes the code very ugly, my implementatio...

I'm really sorry Stef, I forgot to copy the updated version of my homepage on my flasher which means no source today... :( 64KB because 2x 8-bit registers form 1 16-bit reg which can hold numbers from 0...65535. Bank changes are automatic so no 32KB limit. I was wondering yesterday, that what might ...

Now I see...

I have written the startup code (and the rest) from scratch. My joypad code just stores the result in RAM.
