Running a different R4 firmware on Original R4?

[TheSegaKid]

Hello, this may be a stupid question but is there any possible way I can run the R4iTT firmware on the original R4, or atleast any other flashcart?

R4iTT firmware is fundamentally incompatible with original R4. Not to mention, with the existence of the official Wood R4, using R4iTT's version of it is unnecessary (and also less of value in terms of game compatibility.)

There are 3 kernels for the original R4, not including TWiLight Menu++:
- The official one (not recommended, last updated in 2008)
- Wood R4 1.62: https://flashcard-archive.ds-homebrew.com/R4_original_M3_Simply/R4DS_Wood_R4_1.62.7z
- YSMenu (use R4-Clone folder): https://gbatemp.net/threads/retrogamefan-updates-releases.267243/
