Hello everyone
After coming across this beautiful subject!! In any case, thank you to those who contributed to the creation of a personal cartridge
I made mine, it works, but I have a small problem. When I start a game I come across an error, press the c key, the mvs restarts and the game works!.I guess the problem comes from the source. I have a JS28F256
I followed the misos procedure, I'm not sure I did it right.I used romwak I split the file in two and when I concatenate
Example srom=srom1 and srom2 then srom2+srom1=srom
I don't, it's not if it's done well. If there is a better explanation of the procedure, I'm all ears.
I but a screen of the problem
![]()
I'm experiencing the same issue with mv1f 1 slot. Although not on all games, kind of random.I think this is actually a bug in the original menu system (not sure about the new one) that only seems to trigger on multi-slot boards when you select the game. Same thing happens with mine.
When I select a game, I get that screen, I press C and I can play perfectly.
The cart is working fine on a mv1fz and mv1c.
At first I thought it could be some dirt on the cart slot, but I've clean it thoroughly and get the same green screen. All other original carts play just fine.
