For all of those who are after the latest GP2x WIZ Firmware, here is v1.1 for your records and of course for your WIZ too 🙂

Official new update:

How to upgrade
1. Extract and copy files to root folder of your SD – (6 files – polluxb, uImage, uImageUP, update.gz, vfat.img, wiz_ubifs.img) * You’d better have 1GB freespace for your SD since total size is about 800MB.
2. Insert SD and turn on your Wiz with pressing R button
3. You can release R button after upgrade screeen appeared
4. Upgrade will take about 15 minutes
5. You must re-calibrate your touch-screen; the previous value is initiallized.
