Subject: [SDL] [PATCH] ML-8866 PS2->USB converter
This converter seems to go by several names -- Super Dual Box, Dual
USB Joypad, and who knows what else. Also branded differently with
different colour cases, etc. But it seems to all be the same
internals. It is a common converter used for StepMania, with several
posts Googleable trying to make it work in Linux. I got mine
yesterday and wanted to play stepmania, so I went ahead and made a
crude patch for libsdl to split this baby into two logical joysticks.
A couple notes about the patch:
This patch works well for two dance mats hooked up and playing
stepmania, however the mapping of the other buttons may be off. I
have no joystick which uses all the buttons the converter reports, so
I have no way of testing them.
The name I used 0925:8866 which is the USB ID, and what SDLjoytest-GL
reported is the name, even though lsusb shows Wisegroup, Ltd MP-8866
Dual USB Joypad, and the existing virtual joystick mapping uses the
Wisegroup... name. Not sure why the discrepency.
I'm not subscribed to this mailing list, so please CC me on any
comments to this.
