Here's the official LS139 hookup for a 1A3B-11 (LoROM) cart, to get you started. Only supports up to 16Mbit. http://i39.tinypic.com/b8jwqr.png Wow, thanks for that! Though, it looks like I'm gonna have to shell out an old pachinko game to make the flash cart then, to get the CIC, and that's what I ...

Assuming you're interfacing via the cart edge, you can not ignore the address decoder (MAD-1 or LS139 or whatever is used for decoding purposes). Another possibility would be to design your cart with the microcontroller on board, similar to this project but with the whole cart, rather than just the...

Yeah, I'd like to leave my console intact

I have 2 consoles: SFC and a modded PAL SNES with region and 50/60Hz switches installed

Hey, I'm starting to develop a rudimentary flashcart for my dev needs, and was wondering on some solutions. My idea is simple, just a flash memory and sram for saving(there will be need for bus level shifting etc), nothing more, nothing less. The programmer would be a cheap stm32 mcu programming the...

I'm sorry for bringing this old topic back up, but I'm actually interested in designing a pcb for these, as there are no know, cheap mmc1 replacements and making one involves using cpld's, which maybe aren't that expensive, but learning to implement those would require a bit of time, which i current...

So every game up to 2MB in size, without using any special chips should work without a hitch?

I come to you with a request, I can win a Kaspersky Antivirus 2008 Pack. If in the next 14 hours i'll get enough votes to get into the top5(right now at 23rd place). I'll be very happy with every vote. You can vote by clicking the link below: Tiny link: http://tiny.pl/83n4 Full link: http://legalne....

Hi I'm looking for the pinout of the CPU installed in the SNES, the Ricoh 5A22. I would be very happy if someone here could provide me with one.

Cheers

We're not doing the same thing, you're editing teh J rom to have English text, I'm editing the E rom to have Japanese text(and japanese graphics). What I'm doing this for? The E version runs on a standard MMC, while the J uses sunsofts custom mapper which is harder to obtain. Simply I want to get th...

Hi, sorry to dig this up, but I'm trying to do the reverse thing! I want to get the japanese text and graphic into the european version. I got the graphics, but they screw up the intro screen. Now I would like to ask you to insert the japanese script in to the european file, cause i cant seem to do ...

Why would i need such a switch, and what is h/v mirroring? I haven't got to that part of NES Assembly.

Tokumaru, on a side note, if I pm'ed you, some of my problems(instead of spamming the board) could you help me resolvce them? I understand your posts the most.

EDIT : Just for a thing, I guess it's harder to do a NES cart that a SNES cart because of all it's mapper and bankwitching stuff. The SNES have only 2 configuarions possible (among the very few games using special chips), the NES have at least a dozen of 'standards' configurations, along with more ...

A completely new PCB; drawing the tracks on a laminate. So if anybody has some ideas or info on how to do this, please post it

Ok, i thought of doing a cart for the NES, cuz i have made one for the GB and SNES HiRom But when i see the cartridge connector pinout i'm just going crazy :p Where to connect chr rom pinouts? where to connect prg rom pinouts? I'm going to use just the first couple of adress lines of a 29F040 (got l...

HA! I've made it! I'm so darn happy :D I loaded the pallete repeatedly, with: white ; 30 red ; 16 black; 0F blue; 01 And here's my result: http://img440.imageshack.us/img440/2672/qw6fs.jpg Thank you everybody for the supportive help. Now(tomorrow) i'm going to go with name tables, and assigning pale...
