0.130u2 [Luca Elia, Uki]

0.119u2 [Luca Elia]


< Japan >


Bugs:

- No winning in the auto-tsumo mode after reach. dyq (ID 03209)


WIP:

- 0.135u1: Nightsoil improved dipswitches in Mahjong Vegas. Added 'Show Clock' dipswitch.

- 0.130u2: Luca Elia and Uki added Mahjong Vegas (Japan, unprotected).

- 23rd March 2009: Luca Elia - This unprotected version of Mahjong Vegas runs on royalmah hardware. But, unlike the previously dumped version, it does not use the internal ROM hidden in the TLCS-90 CPU, so it actually works in MAME. After fixing the very, very broken routine that processes the interrupts in the CPU core, that is (my bad). Thanks to Uki.

- 0.123u1: Added dipswitches 'F-Rate', 'Bye-Byte Bonus', 'Auto-Mode After Reached', 'Background Color', 'Flip Screen' and 'Animation'.

- 0.119u2: Luca Elia added 'Mahjong Vegas (Japan)' (Dynax 1991).

- 26th September 2007: Luca Elia - I've added a couple of non-working games, Mahjong Vegas (undumped TLCS-90 internal rom) and Jan Oh by Toaplan (alas, there appears to be a missing code rom). Thanks to Dyq, Bnathan and Guru.

- 30th March 2007: Guru - Mahjong Vegas just arrived, the next haul from Japan.
