please keep in mind that this is my very first attempt at a portable.
so i'm portablizing the RetroDuo and using the zn-40 case. i know that might not seem logical, but i think i've got it figured out as to how it will work. i'll have to have internal batteries, so i'm going to use some li-ion batteries.
i haven't really done much electronically speaking. i'm still gathering all of those materials. however, i have gotten a good start on the case. now, don't laugh. i don't have much experience with a dremel, so some of what i did might seem silly. but it works well for me.
anyway, enough chat and on to a pic or two! this is not my most recent progress. i'm not at home right now where my most recent pics are. this is my progress as of march 7th.

like i said, not good with a dremel. so i thought it'd be much easier for me to just cut out the already perfectly square screen. and it was very easy.

i took this right after i superglued and bondoed the controller holes in. i have since sanded and spot puttied a few times. and in case you didn't know, those two holes under the d-pad are the 8-bit & 16-bit led indicators. i just thought it'd be cool to include them.

i decided to hack apart parts of the retro duo system to use on my portable. this is going to be the nes cart slot cover. this pic was taken right after i simply cut them off of the console. i've since cut them down to the correct size.
that's all i have to show right now. i'll upload some more up-to-date pictures later tonight when i get home.
i made a failed attempt at speaker holes... stupid perfboard slipped. ergh... i was just trying to do it too quickly. so i'll have to fill those holes in and start over.
for those of you wondering about my design, i'll try to explain. i think i've figured this out correctly. the nes portion will slide down the back of the case with the cart sticking out about 1/2" - 3/4" or so (haven't measure exactly). this will make it so i only have to do 1 slot relocation and still have both carts parallel with the case. i believe there will be just enough room for me to have the snes cart actually going inside the casing. i will make another cart slot so that the insides are not exposed.
i want to go ahead and thank Life of Brian and G-force. as you can see, i am basically stealing ideas from both of them.
