Gameboy 1MB 128KB SRAM Power Cart (Multi-game and Multi-save)


This re-programmable flash cartridge has similar functionality as a NPC which supports multiple games with multiple saves using a loader; we re-use the same loader with some patching. You can fit up to 7 games (if they are 128KB or less each) and use the 128KB SRAM which is divided into 8KB or 32KB blocks depending on the game. Designed and made in Australia.

You can’t use this cart for a single game without the loader. Only works with the GBxCart RW flasher.

We recommend you test generate a ROM file to make sure it will fit all the games and configuration you want before you purchase it. To generate the ROM file, jump over to the NPC/iGPC Builder website and select the insideGadgets Power Cart option. You can then flash the created ROM file using the igpc_flasher file found in the iG Power Cart Programs download (v1.5). It works similar to the NPC programs except there is no hidden sector.

When you place an order, if you would like the flash cart to be programmed with a ROM, you need to supply it to us via email (you can reply to your order notification). It will be tested for 20-30 seconds on a Gameboy Advance to ensure it works, if it doesn’t work, we’ll contact you. If you don’t specify a ROM, it will be loaded with the NPC Menu with MGB.
