PSPVE is a port on PSP of one latest version of VecX. VecX emulates the Vectrex game console on systems such as Linux and Windows. It has been written by Valavan Manohararajah.

Changes:

– Major speed improvements :
+ 6809 emulation
+ vector rendering
+ remove vector cash (buggy and time consuming)
– Sound emulation completly rewritten and inspired
from 8910 driver of xmame.
– The rotate 90′ view is now much faster and it is used
as default render mode.
– Save state modification, it is now faster to save state
(but previously saved games are not compatible with this
new version !)
– Add .vec and .gam file extention as valid rom extention
– Add option to change color between gray and blue
