i have been trying everything i can think of, retail disc boot fine but backups that boot fine with tonyhax do not boot.
think it boils down to either bad code that i am using or setting when buring the chip.
figured maybe some here with more experience with pic programming could possibly assist me?
here are some of my install pictures i am pretty sure it isn't my wiring as i have redone it about four times to be sure reflashing each time this being the final result,
(will add from phone in a min)
everything is as short as i can possibly get it, and i have no bridges to speak of.
i got the hex files for the 12f629 from this site
https://www.backoldgaming.com/conso...ip-mayumi-v4-multimode3-mm3-onechip-psnee-ps1
i used the mayumi v4 hex for a usa console as that is what i have. it is a pm-41 psone model and i used the points on the schematic in the files.
i tried mm3 before but was using 12c508a pic chips and the appropriate hex file,
they where giving me all sorts of write errors so i think they may have been counterfeit,
i still have about 6 of those that are "blank" and i kept the oscal val when burring the ones i used.
i suspect it might be these settings that need changing for either hex files
but i have no idea what these should be and can find zero info on google about them in the little info on making your own modchips i could muster up.
here is the hex dumped from my 12f629
it's in the shit.zip file linked below.
i used both a k150 pic programmer and a tL866ii plus to erase and write to it multiple times with no success in getting a backup to boot,
it seems to match the original except the oscal value which probably isn't needed with mayumi v4 but i tried it with and without the value to no avail.
any advice is welcome, i would like to successfully get this going.
