Reflashing Original Firmware on Clone GDEMU

[Ian Micheal]

Bleem does not work on the mode or bleemshell other homebrew does not work so i dont advise mode

It doesn't? Does it not run CDI files? How did they mess that up so badly (considering it's an expensive premium price product)?

Gdemu creator added running of bleem when doing it.. Not really that great to me menu is closed src we have openmenu now and other things coming using Gdemu clone I dont see the point of over paying for it

i have a gdemu clone 5.20.3，it show hardware is the "5.20.3 2021-11-11" print on the board，i tried update it
i already read update guide:
https://www.dreamcast-talk.com/forum/vi ... =5&t=16420
but when first i put the gdemu updater (not firmware) GDEMU.FW to sdcard and locked，seem updater dont work，it just have a blink when dreamcast booting，but not brick my clone，i use blue sandisk 8G
i want know how to update newer 5.20.3 clone?is my sdcard problem?

have you turned the switch on your SD card to LOCK?
Please note, the LOCK switch is mechanical, if you use an SD extension cable it will not work.

no extension cable
yes i have switched my sd card to lock,and it have GDEMU.FW in root
this picture of my clone:

is this type cannot update or it have other method to update?
i tried few sd cards,them can running games but gdemu updater just not work when switch to locked

Have you looked in GDMENU what firmware do you have?
I'm confused by the sticker with the written firmware version, it feels like someone covered the inscription 5.15 with a sticker

Old Clones had a different atmel chip

clone vs original
