I'm still an SNES scrub. Sorry the topic title is misleading af. I just need a bit of help with mmx hacking.
In Mega MAN X, $1F99 is originally 00 which represents 0 upgrades.
This single byte represents 4 upgrades acquired, with each upgrade having a bit value (with the maximum number of upgrades giving it a value of #$0F).
If I tell the SNES Debugger (from BSNES) to break on write to $1F99 at a value of 08, it doesn't stop (even though this value is what the address is set to after acquiring the dash upgrade). I assume it's not writing an immediate value but possibly doing some kind of bit shift.
I am following the dissassembler but I have not found anything yet.
Is there an opcode in SNES that sets the bits of a single byte but does not constitute a "write?"
