New CPS-2 Suicide Tester
Given the new discovery CPS-2 boards can run in a degraded state, I have updated our small suicide test tool to include the small test to check for it.
Download the new version right here.
Suicide CPS2 Game Board Tester v2


CPS-2 and voltage
Many years ago there were rumours and some saying CPS-2 phoenix edition sets (suicide free CPS-2 games) did not run at the same speed as the original encrypted games. At the time this was tested and it was proven not to be the case. Recently this issue surfaced again and I decided it deserved a second look.
Through testing done so far its been discovered when a CPS2 system is not receiving enough power it can run in a degraded state. The 68K CPU is tested and results on such systems show a measureable difference in the expected results. The results show it is possible under the right conditions for games to run differently than the normally expected state.
A voltage tweek is reported to be all that is needed to rectify the situation.
Testing is currently ongoing but if you would like more information, or would like to test your CPS2 setup head over to the following;


Kawaks v1.64 released
I made a new kawaks build adding many new clone games, see included whats new. Get this latest version from the downloads page.


Darksoft releases new CPS3 ISO's
As the title says Darksoft has released some new ISOs for those wanting to play games on CPS3 hardware using a cartridge with a dead battery.


CPS3 can use standard SH2
Despite what some people said darksoft has finally shown CPS-3 carts can work with a standard SH-2 CPU. What this means is all CPS-3 games have been put on a single CD and can all be played via a single CPS-3 cart.


Kawaks v1.63 released
Put together a new kawaks adding many new clone games.... Too much to show here, see included whats new. Get this latest version from the downloads page.


CPS3 suicide free = DONE!!
Like all things its only a matter of time after someone puts the effort into it that these things happen. And that person is Darksoft and Co. As expected it will end up with one suicide free cart to play any of the six games. Big contratulations to you guys!!


New CPS2 information.
idc/Team Avalaunch have provided pictures of the last peice of hardware in the CPS2 encryption key upload process. All that remains is to get all the parts together and working out how to attach it to the game PCB. My understanding is the wiring is missing.

New CPS2 information.
Some light has finally been shed on how the encryption keys are uploaded to CPS2 'b' boards. Hardware required is a PDA, cards of 128kb in size that hold the encryption key and a device that attaches to the 'b' board. I have been passed pictures of the PDA and cards but as yet have no picture of the last peice of hardware.

Lost Email
Can the person who sent me an Email today relating to an all in one black MVC CPS2 board please email their message again. My ISP's online email client had a glitch and the message was lost.


CPS3 game conversion tool
Darksoft has now created a tool which will allow you to convert CPS3 games so they will boot with any working protection cart of a different title.


CPS3 suicide free a small step closer
I have reveived information from Darksoft who claims to have reworked a warzard ISO so it boots using a 'working' SF3 cart. The process involved decrypying the game data, reworking the crc check information and patching out protection. Finally it's all encrypted again using the SF3 keys. He has put a YouTube video up to show his work.
If this pans out it will mean being able to play all 6 CPS3 games using a single working CPS3 cart.
