Pandora's Box 4 is one of the easiest ways to convert a single JAMMA arcade cabinet into a multi game MAME; but is it worth it? With 645 games on one PCB how does it handle presentation, emulation and overall value? Spoiler: pretty well actually.
Note: I re-uploaded this video after identifying (thanks to youtuber 'dankcushions' ) the true function of "Quality Optimization" on the Pandora's Box unit. It's a critical feature to take note of and justified adding that section to the video.
I should also note there is a 10Watt mono amp built into this PCB that you can use. Addendum here retrobuiltgames.com/reviews

Unboxing and overall quality overview of the 27-DVD complete collection released in 2015. This collection is more value than quality, but still a [nearly] comprehensive way to own the Futurama series on DVD.

![Add a Battery Pack to Your Mini Arcade Machine
I take a li-ion battery from a cordless drill and see how to integrate it with my mini Arcade to make a 100% Portable arcade machine.
Battery =Ryobi Li-Ion 18V
In no way is this video sponsored by Ryobi, its just the brand I received as a gift from my dad many years ago. Thanks dad!

![Build the perfect multi-input display for retro gaming and vintage computing.
I designed a nostalgic 3D printable (FDM only) desktop sized multi-format video display monitor. A kit-bash of parts in a style mash-up between a mini Sony TV and the Amiga 1000 monitor. I call it the PixelVision AV-1000 Mk II.
This is an everything input video source device including: HDMI, VGA, component, s-video, and composite video; and 3.5mm stereo audio input/ output. The portable monitor has pretty decent audio with two pairs of built-in speakers and excellent picture quality [2048×1536] with the OEM ipad (gen3/4) IPS LCD panel.
