So i used Retrogamefan's 6.53 upgrade on my r4i clone. (Thanks so much Retro!) The r4i clone i have is R4i-SDHC (r4i-sdhc.com). The pokemon rom works great on it, its just that it has frequent slowdowns throughout my gameplay. For example when i run past NPCs in big towns. Is anyone else experiencing these problems? Is there a way to fix this? Thanks.
