ScummVM-DINGUX README
==============================================================================
Requirements
============
- Dingoo A320/A330
- Dingux installed on SD card
- Fixed Tremor libs in dingux rootfs (see below)
Controls
============
- Dpad: move mouse cursor
- Y: left mouse button click
- A: '0' key
- B: right mouse button click
- X: '.' key (skips dialogue line in some engines)
- Left Trigger: open global menu
- Right Trigger: ESC button, scene skip in some engines
- Select: opens virtual keyboard
- Start: F5 key, game menu in some engines
Installation from binaries
==============================
Mount your dingux SD card in your pc, then copy the directory "scummvm" found in
the release package to a directory inside /pathtosdcard/local/dirofyourchoice
(on windows it would be SDLETTER:\local\dirofyourchoice).
At this point is sufficient to point your launcher (eg. gmenu2x) to scummvm.gpe
file included into the scummvm directory you copied to the SD card, and then launch it.
Building from binaries

Kernel and rootfs WARNINGS
==============================
All the dingux root images (rootfs) i found floating on the net have
broken tremor libraries, which make scummvm crash in a bad way.
One solution is to replace the libraries in your rootfs by injecting these fixed ones:
http://hkzlab.ipv7.net/files/misc/dingux/dingux_fixed_tremor_libs.zip
After having added these libs, scummvm should work on your standard dingux kernel,
but this doesn't mean it will work perfectly:
non-opendingux kernels doesn't have lcd double buffering leading to a lot of annoying
tearing on screen.
The best way to address all the problems in one shot, is to use an opendingux kernel for
your dingoo, which has some interesting advantages:
- The kernel gets updated and kept in sync with main linux tree
- Double buffering and centering of screen image
- Support for swap on compressed ram
I have prepared a rootfs image with fixed libs and swap-on-zram to use together with opendingux kernels:
http://hkzlab.ipv7.net/files/misc/dingux/opendingux/opendingux_kernel_rootfs.zip
The kernel and rootfs images in the zip file is what i use for developing scummvm on dingux.
BTW, i have built images for the A330 and A320 with ILI9325 controllers too,
but these version aren't tested (i have an A320 with ILI9331, but if someone wants to
donate an A330 to a poor scummvm developer so i can try the port there too... :P)
If you need a launcher with opendingux cpu frequency scaler support, you can find gmenu2x here:
http://www.treewalker.org/dingux/cpufreq.html
I've also prepared a rootfs image for use on normal dingux kernels (non-opendingux ones).
It's based on elta's rootfs image with just the fixed libs replaced.
http://hkzlab.ipv7.net/files/misc/dingux/normal_dingux/rootfs_elta_fixtremor.zip
I still raccomand the use of opendingux kernel + rootfs, but if you don't, this roofs
image plus another kernel (eg. SiENcE's one) should be do the job.
Enjoy
