Hey guys.
I recently patched a Mega Man 3 with a "Mega Man 3 improvement" hack by Kuja Killer, and today I tried to make it into a physical copy.
I used my own Mega Man 3 cartridge (TLROM) for it (keeping the original prg and chr chip just in case), and followed the schematics shared here https://thepoorstudenthobbyist.wordpres ... cartridge/ for wiring.
Post patch, PRG is 512KB and CHR 256KB, both sized accepted by TLROM.
Wiring was:
512KB PRG ROM:
Bend up pins 1, 2, 24, 30, and 31
Connect pin 1 to hole 30
Connect pin 2 to hole 24
Connect pin 24 to pin 16
Connect pin 30 to hole 1
Connect pin 31 to hole 2
and
256KB CHR ROM:
Bend up pins 1, 2, 22, 24, 30, and 31
Connect pin 1 to hole 30
Connect pin 2 to hole 24
Connect pin 22 to hole 31
Connect pin 24 to hole 2
Connect pin 30 to hole 1
Leave pin 31 disconnected
Result:
The cartridge boots>
I see the newly added Intro movie >
and then it freezes.
1st thing I did afterwards was to check the soldering. Redid a couple wires that didnt seem solid and still nothing.
Afterwards I read the whole changelog of the Romhack, and the only thing that seemed suspicious is that at some point it says "SaveRAM Enabled".
Which makes me wonder if I should maybe use a TxROM variant with ram? (TSROM,TKROM?)
Do you guys have any other idea of what could be off?
Thanks in advance
