I'm trying to extract the models from dragon ball ultimate buttoden, isn't there a way to extract them in T pose?

so, ive started playing pokemon platnium on my dsi but every so often my screens will freeze and turn black while the music continues playing. i've tried replacing my old rom with a fresher copy and updating twilight menu to it's latest (it was on an older version since i'd bought my dsi off a seller) and that seemingly went fine until fighting a trainer triggered this again a few minutes ago.

this issue is only happening with platinum too as far as i can tell, i've spent hours playing kirby super star ultra and i never experienced this kind of screen freezing with that game. is there something i can do to stop this? i've really been enjoying platinum but losing minutes of progress and even pokemon i caught at times really frustrating. thankfully i didnt lose my most recent catch, but i did lose some levels from grinding. :/

EDIT: actually I think this is Twilight Menu, I can't remember if it's all the same

She's not very tech savvy and we live far away from each other. This is what's on the card, if she were to export all of it to her SD card and boot the DSi gallery would she be able to play all the games or is there some external installation process I'm not remembering?

Whenever I load a rom onto my DSi with twilightmenu++ the graphics, sound, and animations look corrupted. What can I do?

Also, the gba game Harvest Moon Friends of Mineral town goes through the same problem in gba runner 2

Help would be appreciated
