- The image quality ("Coloring" & "Quality of the special scanline of
default") has been improved to become beautiful and easy to play.
- "Set Resume" menu was added to "File" menu. The game that puts the check
in this menu starts from the last continuation when starting next. (Every

of the "TurboButton" setting and the "CPU Speed" setting , etc. return.
(The best setting at each game can be preserved.)

"Bravoman", the problem that the character font takes the shape (generated
from v0.88) was corrected.
- The behavior (screen display) when the "Hu-CARD game" started was modeled
on a real machine.
