In newer editions of the FW, it has an option to use the common files. It lacks compatibility with many new games and it has a problem displaying cheat codes if there are too many. Some older ROM trimmers cut off too much data from the ROM and break download play, along with causing other issues. As of firmware 1.10, the R4 unit patches automatically.
All future Anti-Piracy ROMs are not supported but could possibly be fixed on a 1:1 basis. You will need to rename your save files in order to make use of them. Including Wii-connectivity, Cheats, Themes, Short-cuts, etc. However, it has not been updated since April 24, 2008. However, NDSTokyo Trim is widely considered to be the best trimmer at this time.
This has been fixed with dswifi 0.3d (released 01/29/2007) however not all projects have been updated for this latest release.
128MB compressed games have issues with this CC Pandoras because of limited RAM.Without the Jedi guardians of peace and justice to oppose him, Sidious brought an end to a thousand years of democracy; in its place he installed the absolute rule of himself as Galactic Emperor.For over two decades, opposition to the Imperial regime was ruthlessly suppressed by the rapidly expanding armed forces of the Empire. I won't say it is 100% because there could be the occasional glitch or bug. Firmware 1.18 is the latest official firmware for the R4DS. NOTE: Since the release of Wood R4 and the lack of unofficial updates for DSTT firmware, this firmware is not highly recommended.
