The stock r4i-sdhc.com 1.85b kernel timebomb was removed thanks to the reverse-engineering efforts of kynex7510 from the Nintendo Homebrew server.

This means that if you prefer to use the stock kernel for these carts rather than YSMenu, you can now do so. It also has fake card checks removed, so it works on any cart that is able to run the R4i-SDHC YSMenu - including carts from r4i-sdhc.com, r4isdhc.com, r4i-gold.eu, and others.

Pros over YSMenu:

  • Arguably better UI - (depends on personal opinion)

  • Supports more games: romhacks and some games may work where YSMenu doesn’t.

  • Has RTS with in-game menu (Real-Time-Save, AKA Save States)

Cons:

  • Cheats menu sometimes breaks

  • Cheats are sometimes unstable

  • RTS implementation is unstable
