This tool can build the data necessary to flash new games to a Nintendo Power Game Boy cart. The cartridge can store up to seven roms, or a total of 896KB of game data. For flashing, I recommend the GBxCart.

Features

Add up to seven games depending on their sizes
Five different font options for menu entry, including a JP font similar to the original
Load data from a previously created rom
Built in romhack options, including an english translation patch

NP GBメモリ (DMG-MMSA) Font
- This is an attempt at reproducing the original font used on the GB Memory cartridge. Since the font is not stored in the rom, Lesserkuma has been working to recreate the font by studying cartridge dumps. The font started life as the one used in the JP Game Boy game "Kaeru no Tame ni Kane wa Naru", and has been tweaked to closly resemble the original GB Memory font! Special thanks to Lesserkuma for their hard work!
TWL-IRAJ-1 Font
- A font with support for narrow alphanumeric characters as well as Japanese characters including most Kanji. Suitable for long game titles. Based on a font used in Pokémon Black and White, this font was also created by Lesserkuma.
