Lead dev on 3SX – modern 3rd Strike port. iOS engineer

[apstygo @3sx_dev]

3SX came out of 3s-decomp – a matching decompilation of the PS2 version of 3S from the Anniversary Collection

3SX builds on top of 3s-decomp, porting the game to Windows, macOS and Linux while adding much needed QoL improvements (like better pad support, scale modes, etc.)

@dustytokyo @foolyoldaccount @victoralonso_es The clip shows that per-frame game state is perfectly synced between versions (in this particular replay)

FBNeo doesn't have the best frame pacing logic, which is why it runs a bit slower

[apstygo @3sx_dev]

@LSISSO Proper Raspberry Pi support is Work in Progress at the moment. Stay tuned, I'll post an update once 3SX is playable on raspi

Artem (apstygo) here – lead dev on 3SX, a community-driven port of 3rd Strike based on 3s-decomp

Gonna post updates here so info on the project comes straight from the source

@MarcDWyz When I fix discrepancies, I do so under a toggle. So yes, you'll be able to choose the revision in local play. Online will always use arcade balancing

[apstygo @3sx_dev]

@ThePurpleMatrix Yes, supporting assets from other installments is in the backlog

[apstygo @3sx_dev]

@NeoRussell Don't worry, arcade accuracy is a huge priority

[apstygo @3sx_dev]

@Yetomy_Corp Native ports are usually much more performant than emulation

With source code you can do whatever you want. On the other hand, patching arcade ROMs is much more time consuming, error-prone and limiting

[apstygo @3sx_dev]

@MineCreeperLPs Combo trials are in the backlog, but they'll have to wait until after 1.0 is out. They would be nice to have, but not high priority

[apstygo @3sx_dev]

@Wigort15 CPS3's CPU is Hitachi SH-2. Ghidra does a pretty good job of decompiling SH-2 machine code to C

[apstygo @3sx_dev]

@badjab326 iOS and Android shouldn't be too hard to support

DEMIS98 and giblet have put a lot of effort into porting the game to PSP

@Old_Man_Rukus is working on a Wii U port

Raspberry Pi is a priority too

[apstygo @3sx_dev]

@pr4m0d Thanks for the words of encouragement. I appreciate it ❤️

Regarding decomps. NG and 2I are very similar to 3S in terms of code structure. If you wanna start a decomp of one of these games, come to our discord (link in GitHub readme) and I'll make sure to onboard you

[apstygo @3sx_dev]

@cartola3rd Not a full decomp, no. Just the engine part

[apstygo @3sx_dev]

A huge blocker for the 1.0 release is arcade accuracy

To iron out discrepancies, I built a toolkit that runs Fightcade replays in 3SX while comparing engine state

I'm also working on decompiling the CPS3 version to ensure the engine is 100% arcade-accurate

Current status:
- Reworking project's architecture to make porting to older consoles (PSP, 3DS) easier
- Working on a faster renderer to get 3SX running at full speed on Raspberry Pi
- fooly is building a matchmaking server
