In the discussion about a hacked Game Genie, where it has a bootloader that receives commands from a connected PC, someone suggested using that with a PowerPak Lite, so that no CopyNES is needed. In order to configure the PowerPak Lite with this setup, its registers and wiring must be known, so that the PC can do the same things that a CopyNES does when configuring/loading its RAM.
That also got me thinking, would it be possible to embed a 128-byte (possibly smaller) bootloader in the PowerPak Lite, so that it could be used without a CopyNES or modified Game Genie? I don't have much information about the board or CPLD that it uses, but I believe that a CPLD can simulate ROM. Since the PowerPak Lite supports mappers which use all 8 bits of data writes, the CPLD has to be connected to the data bus. Perhaps it's not connected to the lower bits of the address bus, though. Without that, it'd be very difficult to simulate a ROM.
