Battery will not work on that with most SRAM chips.
Use this one instead, I haven't tested the new battery circuit, but its the same one that the PoorStudent uses so there should be no problems.

Ahh, lucky I asked, would not have realized that till its too late. I guess ill stick with the 629 for now, my parallel programmer can't program that chip. I'm currently designing a truly Universal programmer on the side, guess I'll wait until then. Edit: Now that I think of it, I may be able to pro...

Oops, I meant the Pic10F322.

I'm working on my second revision now, was thinking about using your 10f322 CIC code.
I see it has ICSPCLK/DAT, so I'm pretty sure its compatible with my snap, and i see VPP so I'm assuming can be HV programmed as well, just wondering how you yourself does it.

Hey lidnariq, how do you program the 322?
Do you use a parallel programmer, or something like a pickit or snap?
I have a snap, but I guess either way I'll have to make an adapter.

Hey I got it working!!

I compiled version 1.10 and its working great.

Thank you so much, I would have never fixed it if you didnt mention gpasm and the github page.

Edit: I just noticed there is snescic-key.asm, as well as supercic-key.asm, do you know why that is? Only by comparing the two. Looks like "supercic" includes "pair mode": SuperCIC pair mode: when a SuperCIC lock and SuperCIC key detect each other they both switch both of the da...

On the SNES, I'd call pins as follows: cart 24: CIC I/O #2 cart 25: CIC +RESET (supercic uses falling edge) cart 55: CIC I/O #1 cart 56: CIC CPU clock (either 24576000÷8, in later SNESes, from the APU; or 4MHz, from a 4MHz ceramic resonator) In contrast: cart 57: S-CPU 65816 φ2: only high if either...

]It doesn't use the internal oscillator; it uses the 3-or-4MHz clock provided by the SNES to run... Oh very interesting. So is pin 56 and 57 both outputting clock from the SNES? I downloaded an eagle library for the cartridge board shape/pins, and I noticed somethings are labeled differently than i...

The '675 has an ADC and some hardware that disables the digital inputs by default. If you want to use a '675 instead of a '629, you'll have to include an instruction to fix that. (The supercic firmware for '629 already has this code to keep its analog comparator from precluding the digital inputs: ...

Just went back and did it with the clock to see if I could use a procotol anyalzer on the original CIC, man its wierd.. The clock pulses many many times before anything is sent on the IO line, which each IO pulse being many clock pulses. Had to make another post, wouldn't let me attach these photos....

All good, I really appreciate the help you've given me. I just tried analyzing it, tried 2 chips, a 675 and a 629. The 629 atleast tries to respond but the 675 doesnt do squat. I didn't bother doing the clock, although maybe I should have. Here is the 675 supercic_675_LogicAnalyzer_Data.png And 675 ...

Oh I still have one problem actually, my supercic chip is not working. Flash, eprom and fuses are programmed. I even tried it in the SMW cart with no luck. This is how I connected it on original cart. supercic.png And here is the contents of the 629, flash, EPROM, and fuses. superciccontents.png I'm...

There are a significant number. Any cart PCB code that ends with "0N" has neither RAM nor battery, such as: The SNES provides no save memory; the cost of an additional IC just to hold a save was often deemed not worth the cost, and games either were designed to be played through in one si...

Just a warning to anyone using my circuit for reference, the battery circuit, specifically at Q1 does not work for all chips. I tested it on a breadboard with a flash chip before I ordered my boards and it worked, but its not working with my SRAM chip, the GM76C88AL does not let you sink current fro...

Word is pretty standard for 2 bytes now a days. Dates to the 8086 and 68k, where WORD was appropriated in programmer's parlance for the native data bus width of the machine. (Hence why "DWORD" and "QWORD" mean 32-bit and 64-bit). But in a hardware context, a word is just the out...
