Please help me. Sorry I am turning this into a story...but here goes... The other day I had to make a tough decision when I made my purchase. I am old school and have like a dozen old classic Game Boy games (monochrome) when I had to make a decision...purchase a GBA SP that can play GBA games as well as old school Game boy games, or give up the opportunity to play old school tetris and Final Fantasy Legend I II III by purchasing a Nintendo DS which does not support OLD SCHOOL Game Boy games. I chose to purchase the newer Nintendo DS Lite hoping to purchase cartridges that still contained "Classic NES" games like Metroid and Bomberman...until I found this website indicating that I can purchase some sort of a USB device and card and then transfer my game boy and NES games via a PC or even an SD Card. I have seen like a dozen diferent cards for the GBA or DS and don't know where to start. I am not really looking for one that does DS games, but mainly GBA games including ones that can support a 8,003kb rom called Pocket NES that has over 70 classic "Legal" Roms which includes a cool game that I used to play when I was like 12 years old called Blaster Master. I have already legally downloaded it and would like to know what is the cheapest chip or component that I need to purchase to play this game as well as other Legal HomeBrew Roms right on my Nintendo DS. Do I have to purchase a flashcard? Do I purchase a PassCard? I am willing to either purchase the cheapest one on the market or the best one on the market. I want to play at least GBA games but I would also like to Play Bonks' Adventure on the PCE/TG-16 EMU and or play Sonic the HedgeHog for the Sega. Thanks for the info in advance. Did I mention that I have three GBA cartridges and still have yet to purchase a DS cartridge!? I only bought this DS because it was the new hip toy to play and it would play GBA games like the WPT Poker game that my wife bought me and the Final Fantasy I & II cartridge that I bought myself on ebay for $8.50. I am interested in Final Fantasy games.
