Hello. Don't try to use the software on your device unless you absolutely know how it works and what you're doing (Judging from your question you don't). The reason for this is that if you make a mistake, you will have one bricked MP4 player. I tried to understand the software for a while for the same reason as you - to change the average looking display images, but eventually I just gave up. It isn't worth risking the life of my MP4 player.

Sorry 'bout the bad new, but I would forget about changing the graphics unless you know someone who knows how to use the software (Pretty sure noone does here) :P

If you do decide to test out the software (which I strongly reccomend against doing, as everyone else who has eventually bricked their MP4 players) please post up how you went with it.

Thank you for your reply. Well, its seem that the software is not recommended at all. However, I shall try to locate some other software. Whatever the result is, I shall review them later in this board.
Thank you again for your responce.
Cheers.

I got a KM-200 media player (Sunplus SPCA536) with built -in 512 MB of memory and a expansion slot of SD card. Interestingly, I could not find any specification about how much memory it supports 1G, 2G ??.

Well, I bought a 4 G Transcend X150 SD card to see if it could handle it. Wow, it immediately regconized and formated the card to automatically. I kept adding video and mp3 files to maximum capacity. No problem. Play them, no problem...Hence my player does support 4G !!!

I once tried it but that has been a while. Now mine is somehow broken - a flashing accident (iirc there is a thread in this forum that might help you in case you have a similar problem). Actually the bootloader seems to be still alive. I found out some interesting things though:

* the processor core seems to be MIPS compatible (R3000?) with some opcode extensions. Here is a disassmbly of the bootrom code: http://mitglied.lycos.de/luluba/spca...ormal-rom.html
* There is a dll for usb communication "usb_cam.dll" and I found a matching header file on the net somewhere. This dll basically implements the "usb vendor commands" that can also be found in some ini file that ships with a driver for this device.

Via these commands it should be possible to write software to upload & download data and code to and from the device. I didnt got this to work, but I dont have much knowledge concerning usb programming and stuff, so maybe someone will find out how this has to be done and comes up with firmware tool and maybe its possible to get linux or some other suitable os running on this machine with a little bit of reverseengineering.
