Thanks, i'll check that now

hello all ;) I was thinking a bit about the md homebrewn legality, knowing that the megadrive is back on track commercialy with all those virtual consoles and megadrive compilation game. What's worrying me is the message "produced or licensed by sega" which is displayed by the md2 bios... Maybe you...

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 implementati...

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 ha...

I've the framework on my machine so that's not a problem for me but as Pascal said, that will just restrict use for people which doesn't have it.

64 KB ? I understand the 32 KB limit (68K bank) but why 64 KB ?

i found the problem, thanks for your clues stef , it was that interrupts were still activated when i reset. But i needed to redo all the vdp,vram,... clearing , else my rom gonna glitch. now i'm wondering why the startup code was skipping the initialize of vdp and vram when there's a reset ? I gues...

Just by reading the source code, you can see that if $(A10008).l or $(A1000C).w return something != 0 then you pass all the initialisation process (SkipSetup) and only the RAM will be cleared (the VDP and Z80 aren't re initialised). I guess your main function assumes all is initialised as after Powe...

Thanks
I don't plan to assemble them anyway, just use them as source of information

Do you have the same problem with Fusion emulator and using the soft reset feature ? is your initialisation procedure testing about soft reset (genrally by testing the controller port setting A10008) ?
Maybe your program initialisation states up on the initial power ON genesis state.

impressive so far !
Long WAV file, 8 bits mono
Do you plan to put the source code available ? Can be really interesting.

I might as well post this, since I found a binary I thought I'd lost. First Time Out - 75% Note: I lost the source to this before finishing it, thus, even though it's 75% complete, it'll have to be the final release. Nothing special, just a good oldskool C64-style part. Typically C64 / style demo a...

The main function is just a "main" label for you.
The reason : the sega.s file ends by a "jmp main"

Can there be ASM stuff in your lib ? Yeah, i plan to add some later, but only for critical part. I want to use C when ASM isn't necessary ;) Anyway you can freely mix your ASM code with the lib. Just do a 'main' function in ASM then you call C functions as you want. You just have to repect the C ca...
