I do love that feature on Discord.
And yeah, I think I'm just an appreciative person and can't wrap my head around the intense negativity toward the project/devs on here sometimes. I'm just grateful Reaver/team are making these amazing arcade games playable. Rambo??!! I mean c'mon, who thought we'd be able to play that at home (even sans sfx). Transformers? Pretty nuts. I go to arcades all the time and thanks to TP (and other loaders/Mame), I literally can play most of them at my house. Cool feeling being able to walk around and say "I have that, I have that, don't have that but I got that one!"
Do some things break from time to time? Yes. But that's how it works on every emu I follow. Most emu devs open a PR, the COMMUNITY tests and reports regressions, they fix, merge PR and move to next thing. TP does open PRs but no one is really testing them - smaller community I guess. So they get merged without full regression passes. Obviously, things will break. But then the community can then report them, and they'll try to address them in a timely manner. Thanks to the auto-updater that could be hours, days, weeks, maybe longer. If you don't like it, turn off auto-update or be proactive about noting regressions and updating the compat list. Takes less time than you think.
At the end of the day, just remember this is all free. They don't work on your schedule or prioritize things like you would. Most of it is open source nowadays and feel free to jump in and help out. No matter what, just try to be grateful for you what you have, cause you have a lot of freaking awesome arcades games that you wouldn't without TP, including the ones that magically started working on other loaders weeks after becoming compatible on TP.
