Capcom CPS2 Emulator beta 2 changelog

The Juggernaut of a coder known only to homebrewer's as NJ has released a new version of his CPS2 emulator for the PSP today, as well as posting some new information on his website for for TIFF loader users (those who are using the eLoader). Some say that NJ is not in fact a real person and that he is actually the most advanced supercomputer in the world. That would certainly explain how he manages to get through releases; after all he only updated this emulator yesterday. All we know is that he pumps out some amazing emulators, updating his CPS2 emulator beta today to address some pallete issues. Here's the changelog:

• Made a fix for a new problem that occurred in some games due to a change in the palette processing. There are no changes other than the palette. Even the state save data can be used exactly as it is from the beta version.

Here's the information that NJ posted for eLoader users, so if you've been having issues when loading the emulator with a TIFF loader then check this out:

I forgot to add this to readme_cps2.txt, but when using this under the TIFF loader, please add the text below to the appropriate file. When added to the GTA loader, memory decreases so please don't add it to that version. If you already added this portion for text 5/beta, then all you need to do is change [CPS2PSP_3ccaece6] and the ebootname in the first line.
The value in the first line can be determined through the EBOOT_signature.exe program that is included with eLoader 0.98.

[CPS2PSP_3ccaece6]

NJ has been hard at work trying to fix the bugs from the latest version of his Capcom Play System 2 emulator for the PSP, and you'll be happy to know that all of his hard work has paid off in this, the latest version of his CPS2 emualtor your PSPs. Bad translations have led to a bit of confusion over this release, but we'll do our best to put across to you the updates in this version as best we can. NJ did originally release this emulator yesterday, but after a wealth of bugs were discovered, NJ wiped the file from his website until he could fix the bugs. Luckily for you, the time for this fixed release is now!

Firstly, this version is a derivative of the already released CPS2 emulator test version 5 with added bug fixes. From what we can Gather from NJ's explanation, turning sound off doesn't really increase speed, and if it does it will only increase by around 1fps. Speed and stability have been improved on many games including Street fighter ZERO 2. Here is a translation from earier today, before this version was released:

For the time being, the fixes for the M68000 bug are finished, and now if I can root out the CZ80 bugs it looks like I'll be able to release the fix version. Upon reverting to test 5's Z80, the speed dropped quite a bit, so I'd like to stick with CZ80 as much as possible. The CZ80 bugs are also fixed, I've checked all of the opcodes and found problems with some cycle counts and flag math and have fixed them. Maybe I'll be able to release this tonight?

Going on the above translation thanks to b8a, all of these problems should have been fixed because this version has been released. You should certainly get a speed increase from this, just because of the cleanup of bugs in the emulator - thank you NJ!

Japanese coding powerhouse NJ has just released the newest version of his CPS2 test Emulator for the PSP, updating it to version 5. If you would recall, NJ has sent word a few days ago that version 5 is in the works. Well, now it's here and it's ready for you to download.

We've been told that the cache files (system) that had to be written prior to running the games had to be overhauled. As such, those who will download the the CPS2 Test (and that's most of our PSPUpdates readers) would have to make a new cache file for their game, otherwise the games will load up an error.

Also, the sprite management and processing were re-written anew to improve speed and stability with shooting and side scroll action. Sprite drawing and processing were substantially modified. NJ managed to correct the problems encountered with sprite masking process. He used a method that does not decrease the speed of the system.

NJ has posted some screenshots that show the problems he encountered when running several games (CS Club, Super Street Fighter II: Tournament, Dimahoo, Giga Wing, Progear, Dungeons & Dragons, and Shadow Over Mystara). If you encounter problems, just let NJ know through the comments section.

Japanese coding juggernaut NJ has released yet another version of his CPS2 test Emulator for the PSP, updating it to version 4 and fixing a sound bug. Although NJ was actually planning to give up on this project, due to numerous bugs and the slowdown caused by the PSPs limited hardware, he's still weathering each storm and has been continually dishing out updates. We know we have here a playable version and works well with most ROMS we just tried on it, save for some of the fighting games which have been a problem for the creator ever since he began doing this.

This one surely has gone a long way compared to its initial release which saw father-of-Neogeo-emulators NJ himself doubting if he could work out a solution to some of the earlier problems he has encountered. Well that just shows us how much of a perfectionist he is, cause as good as it is now, he's still feeling a li'l bit unsatisfied with its performance, particularly on the (fighting) games. We saw him perform magic a couple of times already, our faith tells us he'll have a full-functioning emulator pretty soon. Remember, NJ has brought us the Capcom CPS1 emulator beta, the NEOGEO Emulator amongst many others, just believe!
