That's strange because the money spent on a EPROM programmer, EPROMs, and donor cartridges I could easily see that adding up to more than the cost of a PowerPAK fairly fast. I suppose it depends ofcourse on the number of games more than anything else though. Most of my cash goes to my children. Dad...

The mod might work but you'll need to do a bit of rewiring, especially for the /WR pin of the RAM. And with the powerpak out for some time I don't see why there is still SO many people asking how to do mods... anyways. I ask these questions cause I'm dirt poor and the only way I can even build cart...

How about adding a 6264 to make a TLROM have the extra ram to function like a TSROM? I've seen threads about piggy backing on top of the PRG but I'm unsure exactly how to do it. If anyone has diagrams that would be awesome.

I tried dropping a 6264 into the chr rom and it didn't work I know the board is good and so is the ram.

nope, it has a 64k chr rom.

Hey,

I got this SJROM board and I was looking to add CHR RAM to it to make a FF2 cart. Is this feasable?

just wire the PRG just like a normal MMC3 game.

wicked thanks!!

There is a CHR write signal the console sends to the cart when CHR-RAM is supposed to be written to. For obvious reasons, CHR-ROM games don't use that pin. You need to connect it to your RAM chip, but the problem is that some boards don't even have the pin on the cart. It's pin number 56. Look it u...

Wow, very neat demo. I drool just thinking of the future this could have. Mind you it could end up a 16meg NES game.

So any news on that Doki Doki binary?

I think getting SMW reproduced on cart with a normal mapper like say MMC3 instead of that crazy Mapper 90 is\would be like a holy grail in the pirate port game scene for the NES. I've always wondered why SMW and\or Bio Miricle AKA Baby Mario have never been hacked to a more common mapper. They both ...

I wired a 6264 SRAM chip to it using a funky setup I got from the docs on how to add the chr ram to a TKROM mmc3 board that puts a 28 pin ram into a 32 pin chr slot. I was using a plain jane TLROM board to make this rockman no lightboard. Can I just pin for pin drop the the SRAM into the 28 pin slot...

Hey, So I was gonna make a copy of the translated rockman no lightboard game. Info from nintendulator says it's a MMC3 with 2megs of prg and thats it. No ram no nothing. So I burn a copy onto a chip and the game starts sure but the graphics are next to non existant. Anyone got a proper know how to m...

Hey,

Is it just as simple as adding the battery to the spot on the PCB to make a metroid PCB use the battery to make say FF2e or is there more to it?

Ya I did check but I'll build another one and see what happens. Last time I build a galaxian cart was a while ago so it might have been something that simple or it might not.
