For compatibility reason, I think EmuTOS should adapt 50/60Hz refresh rate depending on the selected language to replicate the original TOS behaviour.Eero Tamminen wrote:Thanks, I hadn't noticed that 512k version with the default multi-language setting used 60Hz.

Most european TOS are starting in 50 Hz, so the credits screen is OK, but you would get the same error with a US TOS.
R0X Zero Credits screen works fine with e.g. UK variant of 256k EmuTOS, or if one uses EmuTOS tos-lang-change tool to change 512k EmuTOS default language e.g. to UK one:

As a broad fallback, all european languages could imply 50 Hz, while US language would imply 60 Hz.
