Version (or build number)

agg23.NES_0.3.1_2022-12-07

Steps to reproduce

• Start the Analogue Pocket
• Navigate into openFGPA/NES
• Run Core
• Select a game (I've tested with Super Mario Bros. (Europe)
• Start to play

Expected Behavior

Game is running fine.

Actual Behavior

Game is actually running faster than expected. It can be witnessed both from the sound, playing faster and the remaining time clock decreasing at a faster rate.

Additional Context

No response

Aha. Sorry, it didn't really sink in what you were saying. For some reason I was envisioning significantly faster...

You're running a PAL ROM, and the core does not currently support PAL. Please use NTSC ROMs when you can for now.

Thanks for the very fast answer !

Reopening this, as it does need to get fixed eventually.

Blocked on #32. The Altera PLL reconfig block uses 1500 LUTs, and the OAM implementation is taking 7600. This is also blocking several other features and mappers.

Will this ever be supported?
Some games, like Konami Hyper Soccer, is only released for PAL regions, so no NTSC version is available.

The original core has something wasting a ton of space (#32). Until that is fixed, PAL support will not fit. Fixing this is something I'd like to do, but I don't know if I'll ever get to it.
