Does anybody tell me how to wire CHR and PRG eproms onto this type of board? thanks

so how do you know how to rewire eproms when replacing them with mask roms on boards? i have the pinout diagrems of the different boards but i have no clue what they mean. i was hoping to rewire an AOROM board (solar jetman) and put on the lion king. thanks

what guage wire should i use when i am making repro carts? i went to radioshack and all they had was 22g, which was too big. any place i could order it online? thanks

Sweet, i got it working!!!!! thanks alot for everyones help.

ok, but how do the chips go on the board? i have them with the letters to the right. ok, i made the PRG and CHR files 64k and burned them to 27c512 eproms and attached them to the NROM board but all i get on the tv screen is a black and white scrambled buzzing screen. any idea what im doing wrong? d...

do i type this in or is this an action? im using a willem programmer. thanks sorry, i always forget to log in. the file sizes are 16 k PRG and 8k CHR. So i can just fill up the chip until it is full with the same file and then just solder the chip on with no extra wiring? Yep, just do copy /b file.p...

i dont understand this, do you do this with the eprom software? sorry, i always forget to log in. the file sizes are 16 k PRG and 8k CHR.

i got it, the chip was upside down!! i am retarded, i had no clue that it had to be in a certain way.

hmm, i tried the test hardware and it says Hardware error: Check power and connection. the yellow light is on, so i dont know what could be the problem, because i used it last week for the first time and it worked fine.

I have a willem eprom programmer and everytime i start up the software, the programmer shuts off (red light goes out). i restart the computer and the light goes back on, but then then when i load the software again, it shuts off. i tried emailing sivava.com, but they havent gotten back to me yet. an...

ok i get it now, if it has a battery then it has to have SRAM, so this would be all the zeros. but if it doesnt then it is all $ff. is that correct? i needed this info because i am checking the games for SRAM that dont have a battery to determine what board they would need. Thanks Well, VirtuaNES ha...

oh ok, so does anybody know how to check for this? i use VirtuaNES memory viewer, but i dont know how to check for it. some games it has numbers like 5A and sometimes there are just FF's all across from $6000 $7fff. any help on this would be great! Because Zelda 1 uses an MMC1, required for it to ha...
