Vex3DS

Another emulator port I made for fun. This time it's the emulator of an old console using vectorial graphics - Vectrex.

The original code is from vecx by Valavan Manohararajah.

The source code is on my Github.

Attached there is also a zip file with a set of overlays resized for the 3ds.

A romset to be used with these overlays can be downloaded here. Roms can have .bin or .vec extension.

Installation

WARNING: folder structure changed starting from v0.3. If you update from v0.2 move your roms in the /Vectrex/Roms subfolder

In the the zip file there is a Vex3DS folder with the program in 3dsx format. This folder have to be placed in the 3DS folder. There is also a Vectrex folder to be placed in the root of the SD. This folder has 3 subfolder:

Roms: where you can put roms and overlays
Bios: where the emulator seraches bios.dat (the BIOS file free for non commercial use) and bios.png files (included in the zip)
Skin: the folder contains the default image for the menu top screen

Starting the program you can select a ROM and make it run with the A key or you can run the default ROM in the bios with B.

While running a ROM you can change the screen view with the Select key. In the rotated view, the direction keys are rotated too.

While playing a ROM, the Start key open the menu.

Speed is almost 50FPS on most games using frameskip 4. The sound in crappy but will improve in next releases.

Known Bugs

- Selecting the default bios rom with X key doesn't work

To Do List

- Get better sound
- Reach full speed (50 FPS) with less frameskip
