E has updated his PC Engine and Wonderswan combined emulator for the PSP to v0.80 beta 4. There have been 3 other releases of the v0.80 beta and all have included small fixes as well. This is the most recent of the betas (4) and contains some small fixes and notices. From a rough translation, here are the updated features -

* Name decision final
* Not yet mounted functional large number (?)
* Do not save Swan using in-game functions, use the State Saving that the emulator provides
