Re: [Hard+Soft] Memory Base 128

I think I figured out the entry structure. Some bytes are still unknown. The first 1024 bytes of the memory base 128 contains 64 entries of 16 bytes each. The first entry is the header of the entry list. byte 0 : CRC (lsb) byte 1 : CRC (msb) byte 2 : Total sector count (lsb) byte 3 : Total sector co...

Re: [Hard+Soft] Memory Base 128

A quick note about the CRC check. The 2 subtractions are done because the CRC is computed as the sum of the sector bytes starting from the 2nd byte (ie without the CRC bytes). That makes sense.

edit: Woohoo! I can finally read a complete sector.

Re: [Hard+Soft] Memory Base 128

The routine $76cf reads the first sectors and check it contains a valid memory base 128 header. The header is valid if the following conditions are met: The string stored at $8004-$800e is valid (equals to メモリベース128) The following expression is valid ($f8 and $f9 contains the first 2 bytes of the f...

Re: [Hard+Soft] Memory Base 128

Here's some progress (using Tadaima Yuusha Boshuuchuu and etripator v0.4). The following routine writes 1024 bytes at the bank #0 of the memory base 128. The first 16 bytes are copied from $73b1. Bytes 4 to 15 are the infamous "メモリベース128" string. Unfortunately I don't know what the first 4 bytes st...
