Pipsqueak

THIS IS A DRAFT IN REVIEW. DO NOT IMPLEMENT THIS!

• Version: 0 (DRAFT!)

Pipsqueak is a position-independent patch format. It is designed such that simple ROM formats such as GBA can have multiple patches applied together composably by attaching semantic information to content in the patch such that addresses may be relocated, if required.

Goals:

• A patch format that supports relocations.

ROM overview

This is intended to be a quick and dirty overview about how stuff is laid out in memory in BN.

GBA memory map

All I/O on the GBA is done via a big-ass memory map that goes from address 0x00000000 to 0x0fffffff (roughly). For our intents and purposes, we only really need to care about two regions:

• [0x02000000, 0x04000000): WRAM: This is where the working memory of the GBA is resident. In BN, starting at 0x02000000, this is actually a copy of the save data (SRAM) after it has been decoded.
• This is further split into EWRAM at [0x02000000, 0x03000000) and IWRAM at [0x03000000, 0x04000000), but we don't have to care too much about this.
