I don't often post here anymore but I found this hack and I have to say that I'm VERY impressed (I'm not easily impressed!). This hack is VERY well-made. Kalarie, I implore you not to stop developing this hack, it's awesome and I'd love to see it succeed.
I did find one issue, though - the trading room is broken. If you step onto the chair that starts a trade, nothing happens.
Fear not, though! I used to be a real Firered hack veteran back in the day and I still have enough skills to develop a fix for it. Here's an IPS patch that fixes the trade bug:
****Make sure you patch Orange Islands v3.3 and NOT a vanilla Firered ROM*****
Geeky explanation of the fix: I opened up a vanilla Firered ROM and copied the script offset for the trade chair rooms and just made a new script in the Orange Islands v3.3 ROM that uses the same code.
Strangely, in this fixed Orange Islands patch, Ash doesn't look left or right when you sit in the chair...but the trading functionality does work, I tried it today.
(yes this fix will be outdated in v3.4 if a proper fix isn't done but if that happens and someone does still need the trade functionality, I can just make a new fix relatively quickly if someone wants it)
