- As of 0.139u2, some drivers and options show "16-bit EEPROM set with 8-bit data". Check 4030.
- Haze is calling for mixing issues with *SINGLE* VDP games in toaplan2.c. Check 4044.

Summary

03634: quantum: Draws wrong lines

Description

There is a problem with the vector generator in Quantum (1982) since
MAME 0.108u5. Quantum randomly draws wrong lines (see snaphots or video).

Whatsnew (0.108u5)
Rewrote the Atari vector generators, using the schematics and actual
state machine PROMs. The state machine is now emulated so timing
should be much more realistic. Clipping hardware in bzone and others
is emulated instead of hardcoded. Improved accuracy of clocks and
various other bits of cleanup. [Mathis Rosenhauer]
