Hi guys i need help to find a proper firmware for this R4 i'm using this one on my DSi XL with the firmware on this thread RetroGameFan Updates/Releases so i was using this version R4i-SDHC

But most games just wont star the show either a black screen or that i should reinsert the card on the slot

Try reformatting the SD card here: https://dsi.cfw.guide/sd-card-setup.html
If the issue persists, then try installing TWiLight Menu++ to run the games using nds-bootstrap instead: https://wiki.ds-homebrew.com/twilightmenu/installing-flashcard
After installing TWiLight Menu++, boot it, then press SELECT, and touch the bottom icon on the bottom screen to open TWLMenu++ Settings, then set `Use nds-bootstrap` to `Yes`.
