I've got a PMP that is called "Sunplus SPCA536" according to the CheckUDisk program on this site. It has a software update option in one of the menus and I'm really interested in modifying the firmware. I know noone has done it yet, but I think it would be great if we did some R&D
Anyway, I pulled mine apart and wrote down most of the chip names as well as some other misc stuff:
PCB:
HTX-C500 <----- True "Model name"
2005.09.30
ver: 3.0
LOGIC:
jcatch (tm)
SUNPLUS <----- Yep, definitely a Sunplus media player
SPCA536A-PB111
0532
MOH5430.00
(Most of the following isn't so interesting)
BATTERY:
+ALP505068
-HW531110110
LCD:
388572B001 - XX - 0011431
RAM/ROM?:
SAMSUNG 543
K4S281632F - TC75
S2816 ZLI014DAC
OTHER:

SAA7113H

I've been looking around for information on this stuff, but I haven't had a lot of success. I can't even find a datasheet for the Sunplus chip, only some webcam variant. For the MPX players, how was the firmware decompiled? I've asked the guy at chizon.com for the firmware tools (Purposely vague, I want whatever I can get) but I haven't received a reply yet. Does anyone have the firmware upload/backup software for this player? I'm fairly sure noone does but a post by "Irish Nerd Guy"
HERE suggests that it is available (Too bad he was just a guest...)
So does anyone have any ideas? Here's a pic of my PMP. Does anyone have a similar main menu?
