nemesis.c

0.33b5 [Allard van der Bas]


NOTES:

- Driver by Bryan McPhail and modified by Eisuke Watanabe. Special thanks to Unagi, rassy, hina, nori, Tobikage, Tommy, Crimson, yasuken, cupmen and zoo.

- blkpnthr: There are sprite priority problems in upper part of the screen, they can only be noticed in 2nd and 4th level. Enemy sprites are behind blue walls 2 level) or metal construction (4 ) but when they get close to top of the screen they go in front of them.

- To display score, priority of upper part is always lower. So this is the correct behavior of real hardware, not an emulation bug.
