@anotherthing, And some Game Boy games that had extra SGB features, one example is Space Invaders with a modified version of Space Invaders for the SNES.
Kind of lame that the very last console that is likely to ever have a cartridge slot that can add hardware to the system is the DS Lite due to the Slot 2.
Drives were made by Toshiba and in order to use it you had to install an update to have the ability to play HD-DVD discs. You can, however, use it on a PC as long as you install some UDF drivers.
@SylverReZ I thought it was interesting that there's a thread about adding bluetooth to the NintendoDS and no one has mentioned the Slot 2 thing, especially since I'm pretty sure that's exactly what Pokemon Typing does.
@K3Nv2, There's nothing big about new consoles, it's all about making profit from something you had from over a decade ago that is now 10x times worst.
@K3Nv2, PS3 had OtherOS bundled beforehand until they removed it for 'security reasons'. The goal for OtherOS in the first place was that to avoid extra tax costs they had to label it as a 'computer'. Needless to say, they got sued in court for deceptive practices.
It's that cartridge that works in everything except my DSi, which is what I bought it for. DSTwo works in every other DS/3DS I own, just not the DSi. And all my other cartridges work in that DSi, just not the DSTwo. Pretty annoying.
