SuperModel NX v1.3.0
A Sega Model 3 arcade emulator for Nintendo Switch, forked from Supermodel

What is it?
SuperModel NX is a standalone homebrew (.nro) port of Supermodel, the Sega Model 3 arcade emulator, built on Libretro-Supermodel for its ARM64 recompiler.

Features
  • PowerPC → ARM64 recompiler (JIT), including floating point
  • Game list showing the games on your SD card, settings on the + button
  • Game covers next to the list (your own pictures)
  • Press − and + together during a game to go back to the game list
  • Resolution selector (1280x720, 960x540, 854x480)
  • On-screen FPS counter
  • Joy-Con / Pro Controller mappings out of the box

Requirements
  • Nintendo Switch with Atmosphère (the recompiler needs it)
  • Launch in title mode (hold R while opening a game) for full memory
  • Overclocking (e.g. sys-clk) is recommended for Step 2.x games

Installation
  1. Extract the zip to the root of your SD card
  2. Put your own MAME-style ROM zips in /switch/supermodel/ROMs/
  3. Optional: put your own NVRAM files in /switch/supermodel/NVRAM/ (e.g. daytona2.nv), or set each game up once in its test menu (Test = right stick click)
  4. Optional: put your own covers in /switch/supermodel/Covers/, named after the ROM set (e.g. daytona2.png, scud.jpg)

Performance
Tested on a v1 Switch with overclock. Scud Race holds 60 FPS in races, and menus/attract mode run at 60 FPS. Daytona USA 2 runs at around 47 FPS in races at 960x540 (not full speed yet). For demanding games, choose 960x540 in Settings → Video.

Known issues
  • Some Step 2.x games are not full speed yet
  • Only tested on real hardware; Ryujinx/Eden are not supported
  • Some games may need their own NVRAM or a one-time cabinet setup in the test menu

Will optimisations be possible? Getting 45 FPS on max pc.

Would save states be possible too? It's amazing work. I also sent you PayPal, the bounty I posted in the bounty thread 😘👍

Thank you very much for your contribution!
I still need to optimize the code to get better performance.
Which game are you having this issue with?

You can try lowering the CPU frequency in the General tab depending on the type of game.

That makes a huge difference.
 
I want to thank you very very much for getting this project going!
I forked it and spent time to narrow down the audio crackling issue. After that I did several passes to optimize performance.
Here is the link to my fork.

I also want to remind everyone that this wouldn't be possible without all of Tonii's hard work.

I appreciate the improvements you've made to the application.
I've uploaded version 1.2.1 to my repo with your collaboration!
Post automatically merged:

SuperModel NX 1.3.0 is out!

New: game covers
The main menu now shows the cover of the selected game next to the list.
Covers are not included: put your own pictures in sdmc:/switch/supermodel/Covers/, named after the ROM set like the zip (e.g. daytona2.png, scud.jpg). PNG or JPEG, any size. Clones use their parent's cover automatically.

Menu improvements
  • Settings tabs now fill the full width of the screen.
  • Cleaner game list: TITLE, ROM NAME and VERSION. The CPU speed is still set automatically for each game's board (Core → Auto).
  • Slightly smaller font in the list, so all the columns fit.
  • Column headers can no longer be selected with the controller.

Also included (since 1.2.1)
Big thanks to Thorhax for his audio and performance work: crackle-free sound, no more render stutter, and Scud Race now holds 60 FPS in races.

As always, no ROMs, NVRAM data or covers are included: provide your own. Launch in title mode (hold R while opening a game).

Feedback and bug reports are welcome. If something doesn't work, please attach your Log/Supermodel.log.
