I've busy for the last few months with this project that will be integrated into the 240 Test Suite. I am excited to hear what you guys think, and how I can improve it.

Here is a small description of what it is:

MDFourier is an open source software solution created to compare audio signatures and ...

80 sounds good to me as well, please let us know if a paypal payment is needed.

I am in with one, this sounds great.

Thanks TascoDLX, here's the updated code with the ones I could figure out:

Of course Luke, I did add a small note on top of them, and never added any licence or claimed autorship of them. I am also not linking against them so they wouldn't be affected anyway.

Adding the extra notes now ...

Thanks a lot guys =)

Just released the Sega CD builds, will work out to try and squeeze the rest of the colors.

Everything is working now, it seems that the problem was the DMA copy all along.. complicated by variations on the segacd.s code. Here's the final files that do work:

Thanks for teh help, tiles are now being loaded correctly. However it is still crashing. I need to remove the jump table code I made, and add the VBLANK code described above. How could I set _HBL TascoDLX? I did find that bit of code at http://www.retrodev.com/segacdb.asm but it only had that and I ...

Changed the code to clear the RAM before, no difference there.

I am using DMA in my original Genesis code, from your question I take I shouldn't do that.

OK, it is still not working. I've learned a lot more about 68asm today, and played a bit more with it, however it is still crashing hard. I now know my code is being loaded and executed, however tiles are somehow misaligned on VRAM as posted above.

Here's my segacd.s code, which is loaded at ...

Excellent work so far, one of my favorite games on my fav console =)

Just gave it a long spin on the Everdrive cart, it brought back the memories.

Did the stars look ok (not flickering)? I'm doing direct video memory writing so I'm curious to see how these emu's handle it.

I used real hardware ...

OK... I just removed the vector table, and ran it.. it is loading.. but I do need to load the HBL and VBL.. will figure that out then next. What i do know now is that it is executing from the correct address.

It is now loading the font and palettes, but that's all for now. Great advance anyway ...

And the mcd.ld I derived from the original md.ld included on the devkit.
