Would a 3.5" car rearview screen have good enough resolution to play gamecube games without looking pixelated?

You can but some games text will be slightly hard to read.

As a response to the super joy have you ever heard of a powerjoy? They are much smaller and more effective for building an NESp

They're all pretty much the same.

Hmmm can I use Atari Lynx LCD panel?

Can I use those $150 Ti graphing calculator with color screen?

not listed on the first page. j/k

Many portable DVD players can be used as many of them has A/V input. Depending on the design, you may need to leave the DVD board intact (OK to remove DVD motor and laser) and either hard wire the A/V in/out to be input only or switch to external input only (both should disable onboard DVD functions).

5"-7" portable DVD that won't play DVD but has working LCD can often be found for under $10 plus shipping. Keep in mind older game systems don't look good when stretched on wide screen so check for 4:3 panel for older game systems.

Most 4:3 LCD panels for portable DVD player are using CCFL and would require LED mod to get better battery life. Widescreen LCD is a hit or miss but older, broken players are likely using CCFL as well.

Any idea if this screen would work for a portable...
