MiSTer FPGA Forum

I've been trying the Pong core, https://github.com/MiSTer-devel/Arcade-Pong_MiSTer

I don't know why, but the ball is completely wrong. I see three balls flickering and it's unplayable.

Am I the only one having that problem?

Core has been ported from real HW as-is without adjusting for FPGA requirements. So it may misbehave. Current build works fine in all my MiSTers, but i'm not excluding it may work wrong in some cases.

I suggest AY-3-8500 MiSTer core. It's also Pong. It works much better and has additional options.

Actually, it seems that the problem was introduced in the 20200127 release. Downgrading to the 20191228 version solved the issue for me.

I tried lots of video-related configurations in the ini file, but none of them helped.

The intention was to play the original arcade Pong, so using the AY-3-8500 version kind of defeats the purpose

it doesn't contradict my words. Core isn't properly written for FPGA, so some builds may work and some not. It doesn't mean non-working build has bugs. It's how cores are "working" when they are not tuned (asynchronous cores) for FPGA.

The latest update solved it!
