You can get really cheap eprom eraser on ebay. You can order from china with free shipping for less than 15$. Would beat the hell out of leavimg your eprom in the sun:D Also, I always wondered if building a UV LED arrays would work for erasing eprom... I have a load of UV LED at home but was always ...

Well thanks guys, I'm ordering right away and will keep you updated!

I guess the easiest thing for me would be to try to locate a similar ram chip that use 5v then. I'll look around the net tomorrow and try to order one. But I seem to remember that finding 5v IC was much harder nowadays... Is it a matter of just swapping the part with matching pinout or is there anyt...

So I just connect a 1.uf cap between VCC and GND (which should be pin 1 and pin 32 according to datasheet) on the RAM chip? I'll try when I get home. Will let you know how it goes! Edit: ok I re-checked the datasheet and either I didn't look properly the first time or it was the wrong datasheet, but...

I already have two 60 to 72 pin adapter but Kevin seem to say it's not possible to just fix it with voltage regulation. That's basically what I was trying to do, find a way to modify the circuit to make it compatible with regular Nes and Famicom. If I knew what to modify I would but according to Kev...

That's too bad... I was planning on dumping the flash but I'm not sure if it's worth it. I guess i can just play it on a clone, I just don't like having a crap console just to play one multicart. I also bought one extra for my brother who recently purchased an old nes while feeling nostalgic and he ...

Thansk alot for checking it up. If there is any modification I could make to the cart to make it work I would be very happy. Do you think it would as simple as adding an extra zenner diode on the extra empty pad to make it work properly on a NES? I need to take a closer look but I don't remember thi...

At this point I will probably change my mind and go for a full kit instead of just a PCB so you can put me down for one.

Here you go, if they're not clear enough let me know and I will try to take some more pictures later as those were taken quickly for my personal reference while I was opening the cart yesterday before knowing someone would need to check them out: http://www.skinnyv.com/Cart/245in1/ As you can see th...

I made sure that the contact were lining up properly with the famicom adapter (as those cart have shorter edge connector than usual) and tested with a multimeter to verify that the contact were connecting properly between the cart and the adapter. It seem to be a common thing these day and different...

I have recently acquired a few recently made pirate cart for the famicom with some pretty interesting game on them and found out that they could only work properly on NOAC based famiclone. I got curious as to what could make them not work on the genuine hardware... I could understand that there migh...

Hehe that's also my only way to dump cart lol. I managed to dump part of my Bio Miracle bokutte upa cart before learning Kevin already dumped a long time ago:) It's only giving me issue when pirate cart are using 2 ic for CHR and did not figure out yet how to rearrange and shift the data for those s...

A good multimeter is a good investment! I used a crappy one for a while but it's now so much easier with the decent one I bought recently. Like Kevin said, it beat the hell out of desoldering everything. Also, i'm usually able to desolder chip from famicom board with a heat gun pretty fast and resol...

Thanks for you reply, it was very informative! The mapper specific info is past my level though but it was till very interesting. CPLD and FPGA seem so fun to play around and I wish I could use them. I wonder how hard it is to start playing around with them but I figured you need to know how to prog...

That's pretty cool, I tought it was a big undertaking to reproduce a mappers with CPLD, but then again my knowledge of CPLD and FPGA are limited to knowing what they are, how to use them and how hard it is to use them is beyong me. I was planning to try it out one day seeing as they are getting so c...
