0xUHE9R9 can't be address. You can only use: 1/2/3/4/5/6/7/8/9/A/B/C/D/E/F .

0xUHE9R9 can't be address. You can only use: 1/2/3/4/5/6/7/8/9/A/B/C/D/E/F .

Nice to know someone actually knows how addressing works .

On-topic: is this a game error that you get? Or is it a hack/trainer that you're using that won't work?

If it's a game error that's impossible because as lovro said that can't be an address .
