Sunplus SPMP3050A - General

I tired what you said but it didn't work. I think my PMP uses different type of firmware.

Maybe! Are you sure that your chipset is a 305x?

The 90% of the FW I've proved doesn't work in my SPMP3050a!!!

Yes. I open it and the big chip had sunplus logo and 3050 written on it. Can you edit my firmware so i can play gbc games too. Because nes games are a bit boring.

I can't edit the firmware because I don't have any information about CPU and hardware

Finally, some documentation about Sunplus 3050 :shock:

after lot of search in chinese, here is the datasheet:

Hope it is useful for developers :idea:

Nice, is the schematic of a demo board. But is not the datasheet of the spmp3050!!!

For "touch" the FW we need the specifications of the microcontroller!!!

Well, some other discoveries:

My new mp5 (looks exactly like the pic in the first post..)
CAN play nes, gb, gbc and .bin (no gba or anything else)..
Judging from texts and file sizes, I believe the code for this emulators is hidden somewhere (in ROM perhaps?) of each device!!
(the files are just too small and contain only messages)

Moreover, I found out that most .BIN files in folders in A\RO_RES\SKIN1
can be opened with Notepad and all settings for displaying stuff is there!

You can also set the default folders for the machine to use
by altering file SYSPATH.BIN at RO_RES/SKIN1 !!
By using other skin2, we can change between two folders this way 8)

At A\RO_RES\SKIN1\desk there are gfx for a File Browser, but the fw doesnt use it... :!:

So, if there is a good programmer, I think it is easy to
make a skin creator for this mp4 :idea:

Can you please upload the new mp5 firmware please?

The pmp i have do not have dictionary do you think if i copy the dict files from other firmware to mine will work?
I wish to add more features like time, radio, dictionary, tv recorder, and improve camera. Please if some one knows how tell me.This is my fimware.

googling around with some of the filenames as string, I came across what seems to be a developer forum for chinese firmwares and the like. google did a surprisingly good job at translating those pages into human language :P, so give it a try... you might find some useful information there...

http://translate.google.com/translat...sl=zh-CN&tl=en

This actually seems to be the firmware-updater-heaven! only catch (big one) is that you cannot download anything, or register into the forums... at least I couldn't.
Somehow, I got to see a Vssver.scc file, and that seems to be a tool used to maintain/distribute the fw source code among different developers. that's a visual source safe file, which is a windows tool... although all the binary files seem to be made using some sort of unix system, not sure. hope it helps any programmer/programmer-wanna-be out there.
cheers!
