really nice demo! thanks for your work

few reports from people:
on Sega Magic Drive Pro (MD3 clone) 1st part shows half of text info and hangs.
also on GensGS and Gens Rerecording 1st part hangs after pressing start.
2nd part works fine for all.

Thanks for the comment

Yeah i discovered the problem on Gens, it could make some troubles on real hardware depending some timings. Normally you can redownload the rom and it should work perfectly now

I don't know what is the problem on the MD clone though :-/

I added a 8 MB version, indeed the hacked emulator do not support DMA from source > 4 MB version so i modified a bit the code to take care of that.

See the first message for more details.

Amazing!
Blast processing

Maybe for 'benchmark' mode add a count of frames/lag frames?

Works on my Model II with 32X attached.

the 8 MB fails on my Mega everdrive (On a model 1 genesis)

. I either get a solid colored screen, a screen with snow on it with scrambled letters, or a screen that says "address error" then "illegal instruction !"

P.S. The split 4 MB files work just fine.

It looks great! I wish I could get the 8 MB one to play, so I can enjoy it uninterrupted

djcouchycouch, semms to me you've got an everdrive right?

On mine, this rom (8Mo) return me this message : error 141 when i attempt to load it...

The 8 MB rom cannot work on basic everdrive (even the 8 MB version) but theoretically it should work on Mega Everdrive as it does support unbanked large rom (<= 10 MB).

As i don't own i Mega Everdrive myself i cannot test it directly. I used a hacked version of Gens which support large rom but with some limitation (as no DMA on source address above 4 MB).
You said the error is not always the same... at least it sometime display the intro text ?

Sorry, I meant the last non 8MB version works on my setup.

Yeah i know you were speaking about the 4MB version. I think i know what is the problem with the 8 MB version, i will fix it asap

Yes, sometimes it does, but then it will "crash".

Hope you can figure it out and if you need any testing done, I am more than willing to help.

I spent sometime with it but i think the result deserve it

the only bad point is that i can't make it to fit in 4 MB (i did but without sound and not at full speed :-/).

I uploaded a new version (same url) :
https://dl.dropbox.com/u/93332624/dev/m ... dApple.bin

But i really doubt it will change anything as the version was somehow up to date.
Can you read the text ? or is it all garbled ? someone else with a mega everdrive reported me that text was ok but then it crashs when he pressed start (he also got some weird sound).
I'm afraid the Z80 cannot read > 4MB range... i should try a version without sound to test if that is the problem.
