Re: How to program a NINTENDO POWER Cartridge ?

infinest does it also work with SF Memory as basically its the same chip ? Nope the information written on the SF Memory is very different from the GB Memory from what I've seen in earlier posts. Somebody else would have to program another application for that. Hm, interesting. Ok then, can this GB...

Re: 64M Smart Card and the Chinese Pokemon bootlegs use 3V c

If you don't see any small part that looks like this , I'd bet it's in "3V part will eventually die, but no damage will happen to the system in the mean time" Yeah, it's just the glop, the ROM, RAM, and slightly-too-big-for-the-case savebattery. Board looks not unlike this (pic by "Koji Kendo"): ht...

Re: 64M Smart Card and the Chinese Pokemon bootlegs use 3V c

Well, I have two answers so far: "It'll break your Game Boy" and "Sure, go for it". Which one is correct? The Chinese bootlegs have a gloptop mapper, a 3V ROM chip, and a RAM chip. As lidnariq explained, the difference is whether it's a 3V chip fed a 3V supply voltage or a 3V chip fed a 5V supply v...

Re: Anyone Own an EZFlash IV?

Heads-up: The board is thicker than a standard GBA cartridge.

Re: 64M Smart Card and the Chinese Pokemon bootlegs use 3V c

However, a read operation in a flash chip is ever so slightly destructive to the data, because it depletes the charge in the floating gate of the cell. This is true for flash chips under all conditions regardless of voltage conditions. I'm about 95% certain that is simply untrue. All of the sources...

I need help making a Block Out repro.

I'm trying to make a Block Out repro (128KB) with a copy of Pachio-kun 4 (512KB) and a Winbond W27C020-70 EEPROM.

I don't know what to do with the other pins (/OE and /PGM), how to deal with the bigger EEPROM, or how to wire it.
