 Re: R4 or DSTT?
Forgot 1 last important comparison.
Support
The R4 Team has stopped worked on the R4. There will be no new functionality or functionality updates in the future. Expect only game patches and even then, game patches for the R4 will come out the slowest amongst all current flash carts. Furthermore, R4 is no longer being manufactured by the original guys but by other groups cashing in on the R4's popularity. Therefore,
Support = DSTT win. |
