How do you program the S-rom when the cart comes with a JS28F256 instead of a JS28F512? The chip ID returns a 2222 intead of 2223 and when I dump the file the CRC does not match. The M rom was a normal JS28F512 so I had no problems with that one.

The rom has 1 Megabyte = 8megabit, so you need a 27c800.

Would the decrypted Kof 99 rom from the NeoRageX 0.6 romset work on the 161 in 1? It has all the stuff from the final version but has a 128Kb S-Rom.

Seems like an old problem. Here is a new boot being sold on Aliexpress. And is still using the proto rom.

Original black shells from SNK have a white triangle on the back.

Can someone with a working cart confirm if Kof 2000 is working properly? Mine is working, but the letters are all garbled. It's the only game with this kind of problem that i tested so far.

I'm happy to report that I have solved the problem and have a proper working cart now. Reflowed the P-roms and the cart booted properly. The only problem is powering off the system to choose a different game, but I'm not complaining it's worth the trade-off. Special thanks to RockBottom, Vortex...

Just hit a dead end. Cart doesn't boot. It just goes straight to the check board screen. I've programmed everything, dumped and checked the Cr32 for every chip's content before soldering them into the cart. Could this be related to the CPLDs? I've never used Quartus before, so I'm not sure if...

In my case: C1: 0 errors, C2: 2 errors, V: 3 errors. I thought it was the daughterboard's fault because the cart was working before I desoldered everything.

I see. Thank you. There's definitely something wrong then. I think it could be the stock daughter board because I reflowed the pins on the C-chip and it does not report any errors anymore. I will order a new daughter board. I have a spare non-working cart that I can use for chips, fortunately.

Does the "E" in the TEST menu stand for "Error"? For example I get 1 with a C chip and 2 with a V chip. If so is this normal or will it affect the programming?

Yes, I was playing in AES mode. Is it only in MVS mode that it has no endings? Here's a page with the differences between the proto and the final version: https://rq87.flyingomelette.com/RQ/PP/MOTW/1.html The version in 138 in 1 has some of the stuff of the proto patched and some left unpatched.

I have the 138 in 1, it has the endings, no gibberish text as the 161 in 1 and the correct Hokutomaru scarf color in the select screen. But It has Grant's infinite so it's not the final version for sure.

This brand of desoldering station uses a type of nozzle that is a little bit too wide to fit safely between the pins of the stilt chips. I would recommend a Yihua or WEP station. It uses a nozzle with a flat base and a thinner tip that barely fits between the pins.

I'm working my way through this. I have successfully removed the C-chips with an Yihua desolder station and a 0.8mm nozzle. Unfortunately, I ripped one of the legs off. Can I solder a wire directly from the chip itself to the programmer or cart without problems? Also, can someone tell me how...
