Well, this is a new release of Sonic Battle Arena.
Sonic Battle Arena is a 2D fighting game coded in Lua by TheMarioKarters, Vaza, and Popcorn Devil.
The main feature of this release is WiFi online play thanks to netlib and youresam. This makes Sonic Battle Arena the PSP's first online fighting homebrew!
Remember, this is only at beta stage and is still buggy!
D-Pad Right/Left= Move
O/D-Pad UP = Jump
X = Attack
Start = Exit in-game
1.0/2.0+ Users place SBA in PSP/GAME
1.5 Users place SBA and SBA% in PSP/GAME
What happens is, once you press R at the main menu, you select your character with the D-Pad, then press X.
You'll then connect to Netlib using Connection 1. Be sure your WLAN switch is on!
After you select your character, two things can happen. If someone is waiting, you will join them. If no one is waiting to play, you will wait for someone to join.
To cancel waiting for someone, press start, dont do anything else.
There is currently no way to tell who you're playing, or to communicate with them. We hope to add a chatroom of some sort into later releases.
Also, please use this thread to discuss times to play.
