Nice work. 👍 Turning all the hex values and offsets into simple options will make this a lot more approachable for everyone. Looking forward to seeing the finished version. Thanks for all the work you're putting into it. Every new tool like this helps dig into these systems a little more. 😎

NICE! I'll add it to the list and update file naming convention with how 7zxkv suggested. Good find!

Sorry! Late night. Updated the original post with the missing SRAM files. 🙂 Nothing for Moto GP. I spent quite a bit of time digging through Japanese websites, old forum posts, archived pages, strategy guides, blog posts, and various bits of information that have been floating around the internet for years. I searched Japanese forums, GameFAQs, Arcade-Projects, old Geocities mirrors, Wayback Machine archives, personal websites, wikis, fan pages, and even translated Japanese pages looking for references to hidden characters, time-release content, operator settings, and password unlocks. Unfortunately, a lot of what I found either conflicted with other sources, led to dead ends, or simply couldn't be reproduced on the actual arcade versions. There are quite a few claims out there regarding secret characters, time-release content, and hidden features, but many of them appear to originate from PlayStation 2, PSP, Xbox, or other home console releases and were copied from site to site without ever being verified for the arcade versions. Bloody Roar 3 was one example. I found several references claiming Kohryu could be unlocked after defeating him around Stage 5 and clearing Arcade Mode, but despite repeated attempts I couldn't reproduce it myself, and I suspect the information actually came from the PlayStation 2 version rather than the arcade release. I also came across references to Uranus appearing on Stage 16 and being unlockable, but that mode doesn't appear to exist in the arcade version, leading me to believe this was another case of console information being mixed in with arcade information. Battle of YuYu Hakusho was another interesting case. Multiple sources claimed Koto was a hidden playable character, and some even suggested she might be exclusive to the arcade version, but despite all of the searching I never found any screenshots, videos, operator manual references, or unlock methods that could actually be verified. I ran into several similar cases while researching Moto GP, Technic Beat, and some of the Gundam titles. There are definitely still mysteries left, and I'm sure some information has simply been lost over the years. For this project, I wanted everything to be based on things I could personally verify and reproduce rather than just repeating information that might not actually be accurate. So if anyone has original operator manuals, magazine scans, strategy guides, Japanese arcade books, or information that can be confirmed on real System 246/256 hardware, I'd love to see it. There's still plenty of arcade history left to preserve. 🙂 New Link: here
