Here's the problem. I use a R4i SDHC (the red one that comes from www.r4isdhc.com , the third one on that list - http://www.r4isdhc.com/r4-download/ ) on my DSi XL (ver. 1.4.3E), and while it runs without major problems, I notice several slowdowns on any game (the major offender being Etrian Odyssey III, with a one-second lag every time I enter a battle or I access the menu or a shop, but it's far from being the only one). Those slowdowns manifested themselves when I updated my firmware so that R4 could be used on my DSi XL, so I guess the problem comes from there. Is that normal for said R4i to have such slowdowns ? And if not, how can I correct that problem ? And will correcting said problem will still allow that R4 to be used on my DSi XL ? Thanks in advance.
