MAME Info:

0.75u1 [Pierpaolo Prazzoli]


- Incomplete graphical issues. Source (ID 02277)


- 0.133u2: Angelo Salese hand-tuned background music (BGM) tempo in Tryout thanks to a side-by-side reference.

- 0.131u3: Angelo Salese fixed background colors in Tryout and cleaned-up the NMI firings on coin insertion. Also fixed foreground color offsets, game colors should now be 100% accurate. Also fixed flip X on the sprites, fixed scrolling issues, and added screen disable flag.

- 24th May 2009: Angelo Salese - I've been passing these days to improve old drivers issues. One thing that always puzzled me out the most are Pro Baseball Skill Tryout colors. I was almost sure that they were wrong (yellow baseball field isn't exactly my standard for realism) but I've never seen any screen of the real thing so I've never tried seriously to fix them. Then I've seen something and here's the results. Now I should look forward to find a fix for the scrolling problems... Updated: Fixed the scrolling bugs.

- 0.130: Angelo Salese fixed sound regression in Tryout and removed deprecat.h dependancy. Changed visible area to 240x256.

- 0.79u2: Pierpaolo Prazzoli and Bryan McPhail fixed Tryout - Game now playable. Changed description to 'Pro Baseball Skill Tryout (Japan)'. Fixed cpu1 rom loading and visible area to 240x248. Added 2nd Player and 4-way Joystick. Removed button 3. Added dipswitches 'Coin A/B', 'Cabinet' and 3x 'Unknown'.

- 17th February 2004: Pierpaolo Prazzoli fixed the colors in Pro Yakyuu Nyuudan Test Tryout.

- 13th February 2004: Pierpaolo Prazzoli and Bryan McPhail finished the Pro Yakyuu Nyuudan Test Tryout driver - Game now playable.

- 0.75u1: Pierpaolo Prazzoli added 'Pro Yakyuu Nyuudan Test Tryout (JPN Ver.)' (Data East 1985). TODO: Unmapped reads. Unknown memory areas. Why does it write to rom area? Sprites, colors, sound and inputs.

- 13th October 2003: Pierpaolo Prazzoli sent in a preliminary driver for Pro Yakyuu Nyuudan Test Tryout, it's not working too well yet.

- 11th January 2000: Gansuke from Team Japump dumped Pro Baseball Skill Tryout (Japan).
