Iniche it turns out it is either padding or mapper related the roms yes.
Awesome panda they get smaller when they are unpadded.
Taizou about the wxn emulator. Is it open source or can you buy it on the official website?
Taizou it turns out the iphone clone tweeterman reviewed actually uses the same font all the vt03 games in the pack use.
Taizou they did use the same header format in several nes multicarts i have been trying to decrypt now.
I know it is not related but most of the files i seen on the site are documentation and notes for their isports pro. It is only one page that has their games on it.
Also for subor's website read this page:
http://a8.istudy666.cn:82/sd.html. Before you download the files as it tells you to put the spg and application/setup files on the sd card. It is basically the same for a hacked wii. Also if you wanted to. You could also transfer roms and the emulator to the same sd card. But make sure the emulator is from their website.
First of all the spg293 is just a chinese version of a hacked wii.
