Not sure if it's been requested or not a but Ram search aka Pro Action Replay Cheat Search feature like in Geiger's SNES9x version or ZSNES would round out this awesome emulator's features.

I'm looking a bit more into viletim's N64 RGB board, based on his older schematic here and I'm wondering if I can omit any of the following output signals in order to free up an I/O pin that I need as an input signal: CSYNC HSYNC VSYNC CLAMP VSYNC, I could understand as potentially needing, but is ...

No I was thinking of having a custom chip to replace the Super FX on a custom board, but don't get your hopes up that it will happen by my hands.

That custom FX board looked really impressive but it still uses a real FX chip, I was seeing if there was a clone so it can be replaced in custom boards without getting a donor.

Awesome! Thanks.

The SD2SNES is able to emulate some of the chips (using an FPGA), and the SuperFX has been in the works for ages.

No source code of that fpga is out there I take it.

If the board is that big why not just make a complete new board and use the parts from your donor pcb to populate the custom board? you could add more eeproms on there and keep it roughly the same size and cost would be the same more or less.

Confirmed working straight up, no game genie needed. Powered off system, had a nice breakfast, and came back to all save slots intact. Also can confirm it works with the Justin Bailey patch as well. Great job :) Thanks for confirming! Once the Rom is patched there is no need for any master codes if...

How hard is it to patch the rom then remove the header? an extra 2 clicks of a mouse? But so no one cries about having to do it here is the unheadered version.

Thanks but that is what I use as well as M.E.S.S since that has an amazing debugger and here is the patch if someone would be willing to try it out on real hardware to see if it works. This patch if for a Headered (JU) rom and completely bypasses the check routine which runs literally thousands of t...

Don't assume because I have a low post count that I don't know what I'm talking about. I have cracked many Region checks and other protections on many of these retro systems ( I hack Game Genie assembly codes for years). I wanted to have find the routine easily instead of checking every conditional...

Well, UCON64 strips SRam checks. If it was as easy as "getting the check to show" it wouldn't be so hard to find the data for it. I'm working on a comprehensive disassembly of several games to catch patterns in SRAM checking behavior, I assure you that if you have to ask how to get it to ...

Does anyone know how to make this check for different sized SRAM show up on an emulator like bsnes or snes9x? I could find the routine if I can get it to show (I tried doubling the size of the SRAM file and it played fine) and make an IPS patch for anyone who needed it.
