With many Cave games it is especially important to get extremely accurate emulation because they were programmed with the pushed limitations of the original hardware in mind when making them, maxing them out to the point of slowdown often. In order to get mame closer to the PCBs we can send boards to Phil Bennett and he'll add them to his work list and will be able to perfect things like video timings and pixel data. For example in ESP Ra.De. the game slows down more on the PCB than in mame, and it sometimes has sprites disappear when there is "too much" on screen, and it actually makes a cool looking overload effect on the PCB and a timing that makes survival slightly easier, something obviously important if acuracy is your goal. Something similar happens with Progear and other games. We need a deeper testing by Phil.
I sent the CPS1 setup mentioned here a while ago to Phil, it will arrive in a few days. I hooked up a mix of *several* CPS1 games. He will be able to get a large range of testing done and the emulation updates I'm sure will be awesome.
If anyone has a 1st Gen Cave game PCB they will *loan* to Phil (not asking for donations with these wildly expensive PCBs), let me know, and let's get this emulation of these games perfected so when your board dies your heart doesn't. :-)
You can also donate paypal and I will offer the donations as shipping payments for any board owners who don't feel like paying shipping but will otherwise loan it out. Let's get the accuracy updated.
