Dribbletaint reported in the RS-97 Discord Chat that he was unable to image his new RS-97 with any version of the CFW and identified that it is down to having received a new revision of the device. When attempting to boot a card imaged with any version of the cfw the device stops on a white screen. The device does still boot with the included sdcard/firmware.

Under the battery the version number of the device can be seen printed on the board.

While my RS-97 says RETRO-GAME-v2.0 and is dated 2017.11.18, the one he received says 2.1 with a different date (seemingly mis-dated 2017 when it should be 2018).



Additionally, the bezel around the screen is different, and has some text printed on the right side where the original unit had none:



His unit was purchased from this link: https://www.aliexpress.com/item/Data-Frog-Retro-Handheld-Game-Console-3-0-Inch-Console-Built-in-818-Different-Games-Support/32846555193.html

Be advised that if you receive a 2.1 unit the current custom firmwares will not work with it, and at the least a version with a video driver for the new screen will need to be worked out. Thanks to Dribbletaint to bringing this to our attention and providing pictures.

This was discussed in another  thread but lost in it's many pages. It's a good idea that other users know about this. Thank you for the head up. mods might want to sticky this thread for a time as new users will need to know this information.

It looks like they have changed the LCD driver on the new revised 2.1 boards which relates to the white screen. So to know which model you are buying the newer 2.1 board will have the writing on the screen series number that?s how you can tell the two apart without opening it up.

Do we know the difference of having this new driver?

I have one hopefully soon I will do a comparison between the two I am sure the new one has a slightly different CPU revision with a b on the end.

A few things seem different, I see a few additional small resistors here and there. It's stated that the CPU frequency of this one is the same as the non-b version, so I am curious to see the differences.

Let's hope the difference of the screen driver can be sorted out so that the custom firmware can be made compatible with both revisions.

I have asked Steward but not had a reply back just yet and jay from funnyplaying.com has kindly offered donating a new 2.1 revised RS-97 device to Steward for development if he accepts it. If things go well then  the problem will be fixed i am sure once Steward has the new device.

Update from reading the Baidu forums a member is going to send Steward the Uboot, kernel which are hidden in the first 8mb to probly sort out the lcd driver.

Update looks like they have got the new LCD screen working i know what to do and how to fix it but i dont have the new device just yet if and when i get one i will do a new firmware just for the new devices 2.1 board.

From what I read here we probably will have a third version of the RS-97.

This is the same processor to my old Fiio X1 player. From what I understand its a die shrink with some design improvements for power.

CONFIRMED : This Aliexpress purchase does not include the 2.1 revision of the product. DATAFROG is the only company known to sell it on Aliexpress.
