Please, anybody, compile the emulator!

Also, could you answer some of my questions? Rolling Eyes
Arrow Can I decompile a firmware? (if I'll get it from the manufacturer)

Arrow Can I modify a fimware/rockchip game/rockchip application without decompiling?

I have tried to compile the emulator, but no luck yet, I think it will only be good for RK2706 players, but I plan to keep trying, not much time at the moment I'd afraid.

We don't have any decompiler so we can't decompile anything.
Best chance for you WIZARD is an extractor run as a .rkp application from the game menu to create a backup.
You can mod firmware, but you need a working backup first.

Safest for you is to learn .rkp appliction programming and leave the firmware alone unless an extractor can be made.

Thanks! Wink
However, at the moment I'm not developing anything for player.
Making the new version of Gilraen! Razz It's nearly completed.
You'll be able to create the awesome styles, settings, and more... Cool

My player is compatible with the Ramos T8 and I was able to flash it with the T8 firmware (its called Shoktec x5005) but that model sadly doesnt support rkp-games. Btw, has somebody verified that this firmware for rk2706 does support rkp-games? I havent yet found anything in the source that looks like a rkp-loader. I think the games are part of the firmware ("/application/game/gameselect.c").
WIZARD, I dont know of any decompiler that would produce actuall c-code thats close to the original source nor have I tried to use one (I was replying to a similar question before in this thread). I once read that there exists a "decompiler" for the apple iphone which is based on ARM too but couldnt find a download, there also seems to be a "Decompiler" plugin for IDA. Im using arm-elf-objdump -D -m arm -b binary <file>(assuming youre using windows) to disassemble code, but thats asm not c.

However, it would be easier to compile another parts of Rockchip SDK to get the full SDK
than trying to remake the Apple SDK.

Maybe you should take some elements from RK26XX firmware,
and then try to port. I think it's possible. Razz

#96:   Author: AleMaxx Post Posted: Thu Mar 12, 2009 3:39 pm

Maybe you misunderstood me WIZARD, I wasnt talking about an Apple SDK at all and I dont see any reason to port parts of the RK26xx SDK.
In my opinion the first step has to be to run some own code on the device and that doesnt seem to be an easy task to me atm. If that has been achieved one can easyly dump the whole internal memory space to a file or install a custom bootloader.

i tried to compile the emulator today again but it asked for debug.h i dindnt have! i created one and now im getting many errors in source code!

BTW: HELP ME WIN A MIZU M8 AND FOLLOW THE INSTRUCTIONS IN MY SIGNATURE!

#98:   Author: AleMaxx Post Posted: Fri Mar 13, 2009 5:47 am

I think i once compiled the r7dll vc-project and changed the output from .dll to .exe and indeed it compiled and ran but it didnt show up any window only some text on the console about initializing different things and then repeatedly an error message.
Quote: › initio() (DUMMY)
Enter Main!
Sys Disk Writable[0]User Disk Writable[0]OS Task Switch Error!OS Task Switch Error!OS Task Switch Error!OS Task Switch Error!OS Task Switch Error!

The problem was that there is no source for this specific code, its part of the precompiled stuff in iSource.o/iGlobals.o..., I dont remeber that exactly. Btw, i didnt get many errors but only a few with the other messages just being warnings about using deprecated string functions etc..

Sorry. There was my silly question... Embarassed

wiRe was working on an extractor for Rockchip!

#101: Note Re: Hooray!!! Rockchip SDK! Author: WIZARD Post Posted: Sun Mar 15, 2009 8:08 am

I think that it's not finished.
Also this program could damage my firmware, and I don't have a backup.

Knob, if you have a backup for your player, then test, please! Rolling Eyes

I'll try Acronis, maybe it can do backup for the hidden partitions.

I tried to compile it but It isn't complete enough to compile, not sure how the extractor was intended to work. Sad

It would be easier if it ran as a rkp application, then no problems with getting into Rockusb mode, but such an extractor would only work for players with a game menu.

#103: Note Re: Hooray!!! Rockchip SDK! Author: WIZARD Post Posted: Mon Mar 16, 2009 9:35 am

As I know, all the RK26xx-based players have the game menu.
RK27xx doesn't have, however, there's an application for this purpose.

So, the fact that RK27xx haven't the game menu doesn't make sense!

#104:   Author: Benjy Post Posted: Mon Mar 16, 2009 10:55 am

on my nationite OS-43 which is a rk2708 player its possible to access the hidden partition by copying a file called rkusb.tag to the root of my memory! then i have to reconnect it via usb and i can access the firmware partition and can access the APPDATA, RESOURCE, SYSTEM and so on folders! maybe it works on yours too?!

no

some 26 series have game but no game menu so can not access and pick specific game, it just loads a game by defaullt, player with game menu go to a screen first where you can select a game

some 27 series player have game menu, but not many, the s:flo has a firmware with games menu but its an old one, others do to like vx787 etc etc
