Why not use a PS1 Emulator in Lakka, RecalBox or Retropie with Dance Dance Revolution? #17

Closed mtoensing closed 1 year ago

mtoensing commented 3 years ago

I don't understand why a native Raspberry Pi binary struggles with the on-board sound over HDMI and the speed of the Raspberry. I can use a PSX emulator, and it works over HDMI and a resonable speed. Why does stepmania on a pi have problems here?

Even my original modded XBOX 1 (!) runs Stepmania in full speed. Where is the bottleneck?

It worked for me, no problems (rpi 4B), counter to the docs here.

Can't reach solid 60 fps even with overclocking, low resolution and any other tweak I found. Emulation runs better. I asked why this is the case here: https://github.com/stepmania/stepmania/issues/2079

Ok, this works and is really fast (60 fps on most songs)

I know we're all dying for a StepMania forum to talk about things, but...

Why not use (something other than an RPi)

It's definitely not the most-powerful Dance Game platform.

Why HDMI Struggle

I don't know, man, HDMI & video standards are blacker magic than even most Linux development. I suppose each combination of binary + pi + HDMI cable + HDMI device might play out differently. I wasn't able to get a reliably-working combination with anything I had on hand. I guess I should update the README to be less-absolute about how it won't work. But I couldn't get it to.

Why StepMania Have Problems (in general)

As @mtoensing found, StepMania is actually old. There are a couple derivative and/or successor projects (some run by the same SM devs!) - like moondance - that have more-modern codebases that'll probably work better.

They didn't exist when I started out wanting a dance game on a pi!

Also, the arcade uses StepMania 5.1 - which isn't even the newest 5.3. This was for plugin and feature compatibility... when I started out on this project!

Newer SM releases might work better; you can (in theory) use this project's toolchain to install SM 5.3 by overriding several make variables on the command-line but work hasn't been done to make that easy; the arcade repo is intended as a zero-config; JustWorks; predictable thing.
