Cave PGM work (2010/12/12)

Since the release of MAME 140u2, we (nimitz, austere, and I), have been working non-stop to increase the accuracy of the Cave PGM for you.

Since the release of MAME 140u2, we (nimitz, austere, and I), have been working non-stop to increase the accuracy of the Cave PGM for you.

Today we are proud to display our work, which has the following changes from main-line 140u2:

1.Cave PGM games have been moved to be a subset of pgm, so that manipulating the romsets is not required.
2.ASIC027A ARM code simulation has been removed in favor of proper emulation of the ARM (so that usage requires a dump of the internal ROM, or an alternative such as ASick72 [see below])
3.ICS2115 emulation has been greatly improved, however very small issues with sustain and volume still exist

This work has been great fun for us, and we hope you enjoy the product of it as much as we enjoyed creating it.

As a side-product of change 2, I had to recreate the simulation in actual ARM code. This new code is called ASick72, and so far, recreates the Cave ROM perfectly enough to run all 3 Cave PGM games with no issues.

And now for some links:

MAME Patches
ASick72 (with binaries)

Many thanks go to the testers at #iustek, #raidenii, #shmups, Shmups forum, and MAMEdev.
