Alright, this question has been bothering me long enough... Take a look at your DS Lite GBA filler cartridge. See the microscheme? The question is: what is so important in this microscheme? Really, the plastic cover should be sufficient.
this is just thrown out there, but in the process of dolly-chaining of HDDs, i know for sure on mac but i donno about PC, but when dolly-chaining HDDs on the last HDD you add a little adapter that is called a terminator and it does what it says, it tells the comp thats the last HDD in that chain, sooo maybe its just a terminator or they just wanted to waste materials
k, lets say you have like 4 HDDs (Hard Disk Drives) their all 250 gigabytes each, well you want to dollychain them or mirror them to make them 1 - 1000gb or a terabyte HDD so you link them to gether using IDE or SCZI Cables and put a little adapter on the last HDD that way when the computer reads them, it reads them as a terabyte instead of 4 - 250 gb HDDs...so basically i think that it might just be telling the DS that there is no game, sorry for not being more descriptive lol
