Can user-made mappers for the PowerPak directly access the 32KB WRAM pins? They don't seem to be in the FPGA pinout, even though it has support for WRAM. Does the "glue logic" mentioned in RetroUSB.com's description for the PowerPak connect with those pins?
Can the FPGA support more RAM? According to the CNROM sample project summary, only 4KB out of the 6KB RAM in the FPGA is used (the "FRAM" in the schematics), so does that mean that user-made mappers can use 2 more KB of FPGA RAM, or is that reserved for the BootROM?
How should custom games load up the BootROM modules? Examining the Introducing the NES PowerPak thread, it seems as if the BootROM's code (not the modules, I know they are loaded from the CF card) is at around $Fxxx, but I don't think there was actual source code for the BootROM released online, just the BootROM itself. Correct me if I am wrong about any of this.
