Summary 03628: alpine: Red point on the title screen
Description There is a red point on the title screen since MAME 0.122u5
(see snapshot).

Zsolt Vasvari made a general Taito SJ code clean-up in 0.122u5.
Complete memory map from Nicola's ancient notes.
So my guess is that a size typo was made (1 and not 0 => 1-256; 0-255)
or some sort of decimal/hex.

I found the problem with the red point in mame\video\taitosj.c driver.
For me it looks like a typo (see attached compare pic)
and if you changed in MAME 0.136u4 mame\video\taitosj.c line 275 from:

*sx = taitosj_spriteram[SPRITE_RAM_PAGE_OFFSET + offs + 0];
back to
*sx = taitosj_spriteram[SPRITE_RAM_PAGE_OFFSET - 1];

the red point dissapear.

Please do not assign bugs to other devs. If you were going to work on it, assign yourself - otherwise leave it alone. If you were wondering, there is an empty line at the very TOP of the assign list - which can be used to withdraw from a bug.

Agreed about the accidental error during cleanup.
More so because it fixes Elevator Action.
