Dingoo Dingux-MSX Mod: PixaMod 4/6/11

This is a mod for Dingux-MSX, the port of fMSX for the Dingoo A320 handheld console.
It is based on Dingux-MSX 1.1.0 by Zx-81.
About this mod

I (Pixador) used the great Dingux-MSX 1.1.0 by Zx-81 for some days and noticed that some stuff was running faster than it should be, so despite I am not a C coder I decided to grab the sourcecode and have a look. I figured out that interrupts were happening too often but I didn't know why so I wrote to Zx-81 and he immediately found the problem and told me how to fix it... so I did :)

Some days later Zx-81 released Caanoo-MSX 1.1.1 which contained that fix, but he did not compile a build for Dingux. I then decided to merge the code for Caanoo-MSX 1.1.1 with Dingux-MSX 1.1.0 to have a "Dingux-MSX 1.1.1" (without the Caanoo-specific parts, of course).

Then I kept playing with the sourcecode, fixing some little stuff, adapting it to my own preferences, etc. At some point I found the "Cax mod", another mod of Dingux-MSX written by Cax (Stanislav Borutsky) who, just like me, also fixed the FM-PAC issue :) Besides he implemented a nice fullscreen mode, so nice that I decided to adapt it to my mod. Cax also implemented the code to recognize a megarom by its sha1 checksum, which is something I wanted to do too (first I tried to enhance the autodetection code, but it was not enough) so I just took his code and changed it a little.

Now I think it's time to give something back to the community, so here is my mod :)

Many, many thanks must go to Zx-81 for Dingux-MSX 1.1.0 and for all his invaluable help and patience. Thanks to Cax, too, because his mod gave some nice ideas and code, and made me think of releasing my own mod. Last but not least, thanks to Popolon and Supercarte, author and betatester of msxDS (MSX emulator for the Nintendo DS) for their ideas and motivation.
