Daimakaimura Improvement Hack (PC Engine SuperGrafx) Romhack

This is a hack that increases the number of sprites displayed per scanline by 15% and the resolution by 10%.

The horizontal resolution goes from 320 pixels to 352 pixels which increases the field of view to anticipate obstacles and enemies. It is still less than the arcade version (384 pixels) but the field of view towards the front is now exactly the same as in arcade (the missing 32 pixels are at the back).

Sprite display increased from 28 sprites per scanline to 32 sprites for less sprite disappearance.

The screenshots show some before/after comparison (top/down).

As a bonus I raised the credits to 9 instead of 3 because this game is really difficult. And I fixed a bug with the display of lives when we collect an extralife during our last life.

The patch needs to be applied to a headerless ROM file (I always use NoIntro ROM set).
