Hi, I'm a super noob to the forums, but I've been lurking for a while.
I am an electrical engineering student and avid retro gamer. I am interested in converting famicom carts to english using either official NES rom translations or fan translations. Specifically, I have a copy of Princess Tomato in the Salad Kingdom that I'd like to flash to the US rom version. The reason for this is both as a learning experience, and also I have an A/V Famicom as my primary Nintendo, so the carts look better in there. I have access to an *prom flasher, so really my only barrier to entry is knowledge.
I'm looking at the mask rom pinout here: http://wiki.nesdev.com/w/index.php/Mask_ROM_pinout
My question is on which legs will I need to lift on a 27C64 eprom in order to place in the mask rom socket? If I'm understanding the article, I will need to lift A16 - 19 and bridge them to the place under the PRG column. So for example, I would lift A19 and wire that to the PCB where A17 would normally go. Is that correct?
Also, will I place the eprom so that the lower pins match up? I think pictures would best describe what I'm talking about here.
Picture A:
Picture B:
Also, as a confirmation, which eprom size will I want for this rom?
I think that's all my questions for now, but if there's something obvious I'm missing here please let me know! Thanks in advance for any help you can give me!
