Update of /cvsroot/vba/VisualBoyAdvance/src
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv6577
Modified Files:
arm-new.h
Log Message:
- Changed all the clockticks management. Internal emulation speed should be more accurate now (fixes some games that crashed, like Advance Wars 2 or Tennis no Oojisama 2003), some other should have less slowdown/flickering (Breath of Fire 3's underwater level, Mario & Luigi Saga's intro). Added pseudo-support for bus prefetch (still need to check how it works for all the cases).
