Gameboy payload This update merges CMD_OpenSRAM and CMD_CloseSRAM into the single CMD_ModifySRAMAccess. It also fixes an issue caused by calling CMD_ReloadCurrentBox in gen 2 while the vblank interrupt was still disabled.update
For some reason, the merge broke the Write Cbl Data - CART functionality in the dbg menu.
The main problem is that writing a whole sector of data and erasing a sector is too slow to do in an IRQ handler.
Fix: Move the actual flash writing process to the main loop by creating a function called handleCartIO().
The IRQ handler writes to global_memory_buffer, and the handleCartIO() copies that
data to a local write buffer while the IRQ may still add more to global_memory_buffer.
Then it modifies the IRQ handlers' offset and moves the data that was appended in between to the start of the buffer all while
the IRQ handler is still appending new bytes.
If we end up at a sector boundary, we also do the erase_sector() call.
This was tested with and without the print link and print packets debug options.
Without the print options enabled, we end up occupying about 20KB on the cartridge save. (for 1st stage only!)
Man, this bug sucked. I rate it 1 star!
This commit allows you to use the Write Cbl Data debug option and new Load Cbl Data debug option to dump a link's data to SRAM
or load it from SRAM and pretend like you got it over the link cable.
This is useful for capturing the link process on gameboy and replay + debug it later in an emulator.
