Looking good. Will have to try it out.

I got it. I haven't had time to study it closely (Just got back from work). I tested it on my CRT TV and the games work exactly as I remember. Unfortunately it has glue covering where the ribbon cable connects to the board with the GOAC, so I need to remove this in order to see the pinouts better. I ...

I figure if anybody could help me It would be on this forum, so here goes...

I recently learned about the plug n play Menacer. My understanding is that in Japan it was released by Sega, but in the US it was released by Radica. I read online that internally the "Genesis/video" component is on a ...

This has been my week of seeing amazing scaling on old hardware. Here is an example on the NES. http://forums.nesdev.com/viewtopic.php?f=22&t=12055

Well unfortunately it seems that some MD1 has sound problems, what is the version of your MD1 ? someone on Sega 16 has a NTSC VA2 and experience the same type of sound bug that you. Unfortunately i don't think i can fix that by software...

I forgot to test the sound version. :oops: It is an ...

Success! I tried the 8 MB demo on my model 1 without the CD addon and it worked perfectly, great job Stef!

bobthebuilder>I forgot to ask, you don't have any of the MegaCD or 32X unit connected to your MD1 when you tested ? Large rom do not support add-on to be connected.

Finally someone managed to get it working on its MD1 with a mega everdrive :

I will compare them tomorrow, when I return back to my house from this business trip I am currently on.

Here is an album of the pictures I had taken of the 8 MB demo on the model 1.

I tried Ultimate Mortal Kombat Trilogy and I was able to fight for a few seconds and then it failed. Looks like the model one (or mega everdrive) is not compatible :( . Here is a picture of the error, it was slightly ...

No change with the no sound version. Here is an actual picture of the error message that occasionally shows up.

I got some good news and bad news. I pulled out my model 2's and the 8 MB demo runs just fine on them :) , just not the original model one :( . So the mystery is partially solved, the demo may just not be compatible with a model one (Either that or the Mega Everdrive does something different ...

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 ...

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 ?

Yes, sometimes ...

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. :D It looks great! I wish I could get the ...
