Hi,

This started as a Time Crisis port for the Switch with motion controls, then it turned into a full System 22 port.
It's based on MAME with switch-specific optimizations, and it's 99.99% AI-coded.
I wanted to finish it before releasing, but every new day brings a new Ridge Racer / System 22 port, so here's mine.
This release is a beta, it's full featured but requires some polishing, controls may be messy but you can already enjoy most games and get an idea of what the final version will look like.
Most games have only been tested for a few minutes, so you may run into slowdowns / bugs. If you do, please tell me what / where.

Time Crisis requires a small GPU overclock ("GPU Overclock 384 MHz (Handheld)" in the game's X menu) to be at 60 FPS, at least in handheld mode: it isn't a stable 60 FPS without it (it hasn't been fully tested either).

Each game's enhancements can be configured with X. You can launch a game in Original or Enhanced mode: give Enhanced a try, it looks nice.

The code will be released once it's cleaned up a bit.

We were talking a while ago about the Sega Model 3 port to Switch.
Do you think you could resume the project with the help of AI?
Thank you so much!!!

Hi, it’s still in the pipe, I’ve been working on it for months, but at best it’s not 100% full speed yet like on Scud Race, and it’s way too slow on other games like Daytona 2.

I’ll get back to it soon, maybe I’ll try some per-game decompilation or something similar. AI evolves so fast that things that weren’t working well one or two months ago are working now.

I did System 22 because it was easier to get good performance, and also to learn some things that might be useful for other projects, I’ve got a few other ones to finish before Supermodel, but it’s not dead yet :)
