Here's the situation. I'm the unhappy owner of this R4 clone - http://www.r4isdhc.com/download_v2-0i/ - with RGF's latest version (6.99) slapped on it. However, two problems subsist : - First, some games, namely Pokemon Black 2 and White 2 (as well as romhacks Blaze Black 2 and Volt White 2), still do not work on it, be it on the clone or on RGF. - Huge lag issues, present since I updated the firmware to allow it to work on DSi, and clearly visible on games like Etrian Odyssey III (one second lag each time I enter or exit battle), Pokemon Black and Pokemon White (one second lag for each menu at the beginning of the game, plus the same lags as for EOIII). I tested AP-less and normal versions of those roms, and no change was done. I also tried to use a SD card (2 Go, offered with said R4 clone) instead of the SDHC I am using (4 Go, Kingston), and said lag issues were even worse. Any ideas for correcting those ? Thanks in advance. EDIT : Did some tests and posted the results.
