I just recently purchased a second hand DS Lite. The slot - 2 of the system is corrupted and does not recognise any game boy paks. I wanted to buy a flash cart for the DS Lite and after digging through the site I found that the DSTWO is probably the best option. However, if someone can help me with a few queries then I'll really appreciate it. In a month or so I'm also thinking for purchasing the DSi [or DSi XL]. Will the DSTWO work on that one, too? If yes, will the same games [and save game file] work also? Does it run the GBA/SP roms, too? Since DSTWO is more expensive than other carts, what other options do I have if I'm just looking to play the DS games and the GBA/SP games? And lastly, which is a reliable site to purchase the flash cart from?
