Hi everyone
I'm a new user here and I'm new at electronics in general. I was wondering if you could help me out with a project I'm hoping to undertake. I have a lot of questions. I want to build a portable device that plays gameboy ROM files. For those of you that don't know, these are the full game files that can be downloaded from the internet and played using a gameboy emulator, such as Visual Boy Advance. So what I want to do is build a device like the Dingoo a320, which is a programmable handheld device. Research it and you'll see what I'm after. It has internal memory that stores the game ROMs and save files, a USB connection, an LCD backlit screen and quite a bit more. So I want to adapt that idea to make a gameboy style handheld like this:
Game Grrl -- Portable Nintendo Game System
with an LCD, an A and B button, directional pad and start and select buttons that has an on/off switch, a headphone jack and volume control, USB connection and internal memory for storage.
I'm planning to use this block diagram:
Portable Gaming Device, Fairchild Semiconductor - Global Leader in Power Optimization
This enclosure (with built in AA battery compartment):
**broken link removed**
The buttons will come from a Nintendo NES controller
The headphone jack and wheel potentiometer for the sound and the SPST switch for On/Off will come from Radio Shack
I need sources for pretty much everything else. Any sources you can provide would be great. I'm going to track down a good LCD screen.
Would I be able to use one taken from this?:

The game grrl unit uses that, so it might work but I don't know
I'll be using white LEDs for the backlight as they are energy effecient
But, I have questions
1. The block diagram doesn't show where I can connect the battery compartment on the box or where I can connect an On/Off switch, so where do I do that?
2. Do I need to design a board for this to work? (Like I said, I'm new at this) If so, can I use a printed circuit board from Radio Shack?
3. Also on the block diagram, how should I wire up the volume control?
I'll design my own software for this or just find some that works.
