Hey! Thank you for the kind words! I'm glad that you like it and that its running good for you, I remember some other people had tried older builds on switch and it would crash alot, but glad to see thats not the case now (not sure if thats because of my mod or emulator advancements but still awesome!). Yeah P8 old gen actually uses the thaw animations which is interesting, I wouldn't say they are my favorite in the series but they are still good!
Also of course, i'm always open to answer questions!
1. Right now I can't really give a proper answer, I haven't got even close to figuring out custom mesh/models or even porting ps2 ones to psp, so everything that is in the mod or will be added has to be already in the files for mtx mototrax, thug2 remix, or thp8 psp, as those three games are the only instances of the ns tony hawk engine on psp, and all share the same model formats.
2. Sadly not, all the thaw skater_male items were not leftover in the thp8 files, and the skater_female leftovers don't work with the thug2 ones because they made the rear end way bigger in thaw, and while I was able to get some of the skater_shared leftovers used like the shoes and accessories, hats sadly do not work as they were not made for the thug2 heads so they clip and stuff.
3. I would say yes but I mean i'm always worried about not being able to deliver on it, if its a script related thing, i'm not going to be sure I can do it, and if its like a certain level or something being ported over, well I'm not always sure I can do that level over others that may already be chosen.
4. Adding HD textures to somethings is possible, but since its made first to run on a actual psp, and that already has issues with frame drops on it, I don't want to add hd textures when it would end up making lower end hardware like psp or even people emulating on phones and stuff run even worse.
