With the month of october ending in a couple of days, it looks like developer NJ has decided to do some last-minute updating. The coder has just released version 2.3.0 of all of his homebrew emulators (CPS2PSP, CPS1PSP, MVSPSP, and NCDZPSP), along with a new set of updates.

For those asking, CPS1PSP and CPS2PSP are emulators that allow you to play games originally run on the Capcom PlaySystem 1 and 2 arcade boards on your PSP. MVSPSP will run games originally meant for the NeoGeo MVS, while NCDZPSP will runs games from the Neo Geo CD console. Moving on, here's NJ's latest changelog (translated via Babelfish) since version 2.2.3:

* Sound processing is modified. The Q sound of CPS becomes output in 24KHz fixing, it is not possible to modify frequency. (API which has not been recorded before the header of PSPSDK is used. Referring todetails the forumof PS2Dev. )
* Deleting the option of luster effect from CPS2PSP.
* Jointly using software rendering with MVSPSP and NCDZPSP. Load reduction of line scroll and the like.
* Attendant upon description above, renewing romcnv_mvs.exe for MVSPSP. Being there is no compatibility in cash file, please recreate.
* In addition, has not been remembered how many experimental modification which?

We advice would-be users to be extra careful in handling these emulators, given that NJ's readmes are all in Japanese. You may want to get a Japanese literate friend to help in the installation process. Enjoy the download!
