tip for all: use the keyword "squirrel" when searching for fire red rom, it should give you the right rom :)
Back to Game:
i don't know if this little bug already fixed: i updated a week ago to v457 (downloading without wireless connection and low mobile connection takes a little bit now^^) and tried it today. after starting from my save (i'm on rock tunnel now) i wanted to use flash and instead of flash on my pikachu, it shows just " ÉÀ " - will check current version when i downloaded it later^^
(PS: it shows these code only when trying direct hm from pokemon, between "summary" and "switch" - his attacks are okay in summary. And it may have been correct in earlier versions, maybe a bug after solve another bug^^)
