Questions

Short answers to what people ask first.

Do I need JIT?

JIT is what makes games run well. Without it the much slower interpreter runs. JIT needs iOS 17.4 or later.

Does EspressU include games, keys or firmware?

No. You need your own dumps from your own Wii U. EspressU can load .wua files, decrypted folders, or encrypted ones with your own keys.txt.

Why does a game close on its own?

Most games run out of memory unless the limit is raised. Install GetMoreRam and use it on EspressU.
