0.37b10 [Yochizo]


TEST MODE:

- To enter test mode, press Coin 2 key at start.


WIP:

- 0.133u1: Kanikani fixed note for how to enter test mode in Valtric. Coin1 and Coin2 were swapped, and fixed DIP locations order.

- 0.110u5: Tomasz Slanina added mosaic effect to Valtric. Yes, it looks as bad on real hardware as in MAME.

- 19th November 2006: Tomasz Slanina - Added mosaic effect to Valtric.

- 0.104u6: Andrew Gardner added preliminary support for the Jaleco color blending hardware found in Psychic 5, Argus and Valtric (some functionality is still unknown).

- 0.37b11: Changed Z80 CPU1/2 clock speeds to 5MHz.

- 0.37b10: Yochizo added 'Valtric' ([NMK] (Jaleco license) 1986). Known issues: Mosaic effect in Valtric is not implemented. Half transparent color (50% alpha blending) is not emulated. I am not sure that Argus or Valtric use gray scale effect or not. In test mode, most roms have check sum error. Why ? dipswitches are not completed.

- 24th November 2000: Yochizo sent in a driver for Argus and Valtric, but Argus is not working properly yet.

- 23rd May 1999: J-ROM dumped Valtric (c)1987 NMK/JALECO.
