As I remembered,
GCW0: CPU JZ4770 1GHz, 512MB RAM
RetroGame/RS-97: CPU JZ4760 528MHz, 128GB RAM

But I need to try overclock on RetroGame/RS-97, if success, it is good news for us. :)

Yes, I am using old uboot and kernel but new rootfs.
the first 8MB data in internal sdcard include uboot and kernel, so, you can reverse or copy it to your new sdcard by using dd command.
and your new sdcard must be ext3 in first partition because kernel boot arg is: mmcblk0p1 ext3

good luck !


By the way, you can also load rootfs from external sdcard (GBA slot) at boot stage by modifying boot args:
Code: [Select]
$ sudo dd if=/dev/mmcblk0 of=head.img bs=1M count=8
$ sed -i 's/mmcblk0p1/mmcblk1p1/g' head.img
$ sudo dd if=head.img of=/dev/mmcblk0

Is this device as capable as like the GCW Zero or the Revo K101 in terms of hardware?

Also, looking forward to receiving my unit and putting all this custom stuff on there, Steward. :D

RS-97 is less powerful than the Zero so emulators may not be as good but performance might be like Dingoo A380  with custom firmware?

Hi,
All of emulators are ready for optimization.
For this beta OS, it will include the following emulators:
GMenu2X (Main GUI)
GB, GBC, GBA
FC, SFC, MD
PCE, PS1
FBA, DOSBOX
JinYong, SDLPAL, SDLPAL MHV



Very good work Steward, but no mame? :(

Seagal is already working on mame and if you take a look at steward's github you will see that mame is there as well ;)

You can gain access to the uboot console by overwriting the 4mb kernel with e.g 0. Uboot will then fail to boot and default to the console. There you can set the boot delay. Now you can re-write the kernel to the sdcard and have permanent access.

Updated:
GMenu2X is almost ready (only left usb disk function need to implement) and user can adjust backlight and turn on/off volume in Gmenu2X.
Other emulations is still under porting.
Sorry, I only left one week for this beta OS.
Hope everything is fine. :)

Can you tell me on which linux distribution you are working? I can't get buildroot to compile without errors. I would like to bootstrap into another distro.

@t-link   thanks you very much !

basically, I would like to keep original system.
so, I will program an app for user to switch booting from internal sdcard or external sdard.
new beta OS can be loaded from external sdcard.
this can avoid tear down your RetroGame device. :)

I would like to provide IMAGE file for user to make new sdcard.
any suggestion are welcome :)

I would love a .img file because i want to install on the 128gb internal card and write the image with win32disk. I am sure many others would want to change to a bigger card size too.Opening the device is quite easy and hard to break anything simply just remove card and put new written one in your done.Also you could have a firmware flasher file in opk file format that you can flash to the internal memory card.And for updates you can have a pc flashing program which can flash the device. When it has a new update simply just copy to update folder on ext card and flash will write to internal memory hope this is possible as it would save opening the device each time we would want to update the device.Just ideas here but at least we have a few options keep up the great work.
