I will Try to post pictures for the chr About the ''eproms i had'' i found them on old PC mother boards & stuff i had laying around I don't do magic I wish i did heheheh I have 2 identical 32 pin 128k (SST 29EE010) But i can't seem to flash them even with the UV eraser It was written in the data...

I finished Wiring CHR too I checked your CHr plan Toku & it seemed alright everything maked sens i rechecked to be sure & all the place you note were on the spot. I have found 2 UV 128 kb (that seem to have the same pinout as the 29c040 i will try them Later on with a mmc1 game.. of the same...

my bad again... Grr i learn everyday!!! I thought so to put a 28 in a 32 socket would feel weird & don't take the same. thanks master Toku!!:) Here is the pic for the prg please notify me if anything is wrong http://img378.imageshack.us/img378/9293/pcbmmc1005ux0.jpg thanks!! for your time! &...

Ah damn sorry again for making you repeat... I didn't see the difference in Chr ram & the other one so im doomed again in wiring . great then Bring it on! hehe , so For now i finished almost the PRG... I am clueless for the CHR part tho... I check this? http://www.raphnet.net/electronique/nes_ca...

I did the connection to the A17 on the MMC1 Chip (24 pin) 4th leg I made the connection in the back not on the front like you did either way works... Now for the rest can i base myself on the same wiring as yours? PS: i FOund the original CHR in my drawer it wasn't this one i smashed it was the prg!...

Great About the ''pins touching the board this time i was lucky they ddon't seem to touch it at all i raised it to the point of breaking almost....'' But i will try your rick next time Here is what i got Right ride : pin 1 & 2 soldered together the 3rd< Soldered (this is the one going to A17 (MM...

okay so basicly i should remove the 4 extra holes & put the 32 Pin socket into there? right? exept for the ''pins i need to bend or re wire ? if there is some on the first 2 ones... PS: could you point me to A17 please I wanna know exactly where it is :) So the CHR is left intact? no changes?

Before i start I was wondering the 2 extra Pins on top i need to bend them since they Will prevent the others from entering? I had also i worry since on the board there is 2 dots after the 28th pin &on top too after the 14th... they are probably gounds or other contacts ... i worry if the bent p...

Great so i will do the same Wiring As your PRG socket? the one turned upside down.


Did you have 28 pin too? on your board?
let me know

cause i have 28 need to put a 32 pin socket so i guess ill have to bend the pins or think of something.

great I will check your picture .

& do the same.

will i need to put a switch like you did?


Also , I bought those chip you recommended (at29c040 ) finally didn't mess it up




big thanks!
