Neo Pocket Flash Masta Switch

thingiverse

This is a switch "cover" for the Neo Pocket Flash Masta by [Flavor](https://www.thingiverse.com/Flavor/about) so that the internal switch can be accessed from outside the cartridge shell without using a tool such as a paperclip or whatever you have nearby. It make swapping banks on the flash cart much easier. For anyone wondering what that the Flash Masta is, it's a flash cart for the Neo Geo Pocket (NGP) and Neo Geo Pocket Color (NGPC). Due to the variances in Flash Masta PCB revisions, I've made three versions of this switch in hopes that one of them will work for most anyone out there who needs one. I have two Flash Masta carts, one which used the old Linker that Flavor also provided, and one of the newer models which has a USB port on-board. The switch on each looks the same but my first design only worked on one so I made a slightly wider version which worked with the other. However, this wider one wouldn't work on the first PCB due to nearby components that would potentially be at risk of getting hammered by the switch cover. Additionally, most models out there likely came in an original SNK NGP shell with a small hole cut out to access the switch inside. Since these were hand cut, I suspect the exact location and size of every hole is going to be a bit different. I've tried to design the Slim and Wide versions of this switch cover to fit in either of the ones I have, but YMMV - worst case trim a little more room for this switch to fit with an Exacto or Dremel. Flavor has since released a [3D printable shell](https://www.thingiverse.com/thing:2373193) with a hole in the location of the newer USB models (top left). I printed [lions3's](https://www.thingiverse.com/lions3/about) [modified version](https://www.thingiverse.com/thing:2422485) of this shell for testing and made an alternate Round version of the Slim switch since I could be sure the hole would be in the same spot for everyone if they used that shell. Here's a rundown of the differences: **Wide**: This one works best on my older model Flash Masta where the switch is facing up and is located on the right side of the PCB. Both the base/cover and the switch itself are a tad bit wider than the Slim model. **Slim**: This one works best on my newer "USB" model Flash Masta where the switch is facing down and is located on the left side of the PCB. Both the base/cover and the switch itself are a tad bit shorter than the Wide model. Should also work well if you're using one of the 3D printed shells mentioned above and prefer the flat switch style over the rounded one. **Round**: Basically the same as the Slim model, but with a rounded switch that looks a little nicer when used with the 3D printed shells. These shells are also a little taller, it seems, so I may end up updating this design so that the switch sticks out a little further, but it works well as it is. My only word of warning would be that since I cannot verify component placement on all versions of the Flash Masta out there, use your discretion when installing and make sure there aren't any components near the switch that this cover may push against.
