doukutsu-rs VS twitch-tui

The original 2004 freeware release is still conveniently available on the Tribute site. But if you want something more modern with more quality of life features, you can try doukutsu-rs.

however, i believe doukutsu-rs (a fan-made engine recreation) has cutscene skip, and can be used with the game files from CS+ steam... if you're playing hardmode for the steam achievement you'll miss out on it and any others, though

i wouldn’t recommend NX - doukutsu-rs is a lot better, more accurate and actively supported, plus it supports data files from nicalis ports (ie. allowing you to play with CS+ sprites and challenges)

iOS, no afaik, mac, yes - doukutsu-rs has a native mac port and the original freeware version can be run through wine

doukutsu-rs, which can also be used with CS+ data files (not included, for obvious reasons) and implements a number of features from CS+ (like cutscene skip, support for CS+ soundtracks, graphics, and challenges if you're using those data files, and local 2-player co-op). The mechanics are pretty accurate to the original game, with only a handful of minor inconsistencies which I'm sure will be fixed eventually™ as the engine is still actively in development.

If you want to play the freeware on PC, I highly recommend https://github.com/doukutsu-rs/doukutsu-rs

NXEngine is quite inaccurate compared to the original freeware version. These days you should be using doukutsu-rs if you need an alternate engine to play the game.

You can play freeware and remastered (Steam and Switch) versions natively on Mac using doukutsu-rs: https://github.com/doukutsu-rs/doukutsu-rs

Twitch chat: https://github.com/Xithrius/twitch-tui (needs a little work, but promising)

I've been using Xithrius's Twitch-TUI to see and post to chat via the CLI, but I'll give that a look. Do note that there is still work to be done on the app, but the dev is pretty responsive and is good about working on it.
