My R4 was starting to act up, suddenly thinking the card had been removed in the middle of a game, not being recognized on boot-up, etc.
There were games that would not work with the "current" firmware (1.18), which had not been updated since April of 2008.
I looked at possible replacement cards, and came to the NPlayer at a reduced price of $13 USD each. That was a heck of a lot less than I paid for my R4, so I got one for myself and one for my son.
With the updated firmware (3.04 11/2008), it plays the games that would not run on my R4.
I have experienced no hiccups with anything, and it works well with the R4 themes I had on my microSD. I'm completely satisfied with it, except for one issue: the cheat.dat file presents the cheats in Chinese rather than English. My user defined cheats work fine, though. I'm thinking of swapping the R4 cheat.dat for the NPlayer file to see if they work, and if I can read them in English. If anyone has tried this, I'd appreciate any insight.
Overall, it may be a clone, and one of many it seems, but I still find that it works to my satisfaction. I also find that my current 2GB microSD is sufficient for my uses, so a
limit of 4GB is really not an issue for me.
Just thought I'd pass on my 2 cents.
