Where it says: high addresses (20/21 -> solderpad) needs to be connected on the MBC5

Which pins on the MBC5 is that? I can't tell from the image. Also, is it one wire that bridges 20/21 and connects to the MBC5, or will it need to be 2 wires?

Same thing for me in Chrome.

Anyone happen to have a good list of unreleased game boy and game boy color games, that had rom releases made of them? I can't seem to find much of anything out there.

I bought a couple boards that I am going to try to populate. Is there a 64k sram chip that I can use, outside of using a donor cart? Thanks

What do these boards actually look like?

Does he still sell these? Can not locate them on the site.

I used to have a link to show how to region hack a genesis cart to play on NTSC (of a PAL game) but that board no longer seems to be in service. Does anyone know how to do this?? Thanks

What type of material are these nes dust sleeves made out of?

Ive got one board left, ill give it a try soon

You have to have a broken trace somewhere then. With A13/14 being correctly jumpered to romA16/17, and the 256k doesn't use a CE2. I believe the /WE position is unchanged as well as the /OE and /CE. So what is left is the possibility of a broken trace or a bad SRAM.... Or a bad MAD1 i.c. A13/14 is ...

Okie that was one of the suggestions before it appeared, as I had those marked on the board already, but gave it a shot again and still not working. I tested the battery itself and its at 3.06v

I think in HiROM, RAM A14 and A13 need to be wired to A17 and A16, skipping A15-A13 the way LoROM skips A15. Yes, you are right. I just metered a hi rom cart and a lo rom cart both having 256k SRAM. The hi rom cart, SRAM A13 ---> Rom A16 SRAM A14 ---> Rom A17 Tormentor -this is the answer to your p...

Are you still trying to run that madden game? Maybe you should try a game that normally uses 256k SRAM. Like SIMM City 2000 .... I believe that's a high rom, 256k game... Have you checked for continuity from the cart edge to the SRAM chips address and data lines? If any of your solder pads are brok...

Umm still can't get it going. Tied it to old mask rom, then tried on the diagram mark posted using those A13/14. The game works fine, just won't save. One time I did rewire it, and when I put it in, the continue option was highlighted, but when I tried to load from that, it stated the save data was ...
