0.108u5 [Roberto Fresca]


- 0.141: Roberto Fresca and Darran added clones Jack Potten's Poker (NGold, set 1), (NGold, set 2) and (NGold, set 3). Changed 'Super Double (French)' from a clone of Golden Poker Double Up (Big Boy) to a clone of Jack Potten's Poker.

- 0.140u2: Gerrit Volkenborn added clone Super Double (French).

- 0.133u5: Changed description of clone 'Jack Potten's Poker (set 2) (Coinmaster hardware)' to 'Jack Potten's Poker (set 2)'.

- 31st August 2009: Smitdogg - Darran dumped 3 new sets of Jack Potten's Poker (from New Zealand).

- 0.133u2: Changed description of clone 'Jack Potten's Poker (set 2)' to 'Jack Potten's Poker (set 2) (Coinmaster hardware)'.

- 0.128u5: Changed visible area to 256x232.

- 1st November 2008: Roberto Fresca - After a hard analysis, the Witch Card hardware emulation was improved. Now the double-up feature and the witch game are working! Each time you win a double-up, a little witch with a big number inside is added (maximum 3). When you lose/take credits, a kind of slots game starts. The witches numbers start to run and you have some attempts to win an extra bonus. However, only the spanish sets are full working. The english set was brute hacked to always lose the double-up and avoid the witch game. The Jack Potten's poker sets now have their own double-up game working properly.

- 0.127u8: Roberto Fresca added clones Jack Potten's Poker (set 5) and (set 6). Changed 'Golden Poker (no double up)' and 'Joker-Poker' from clones of 'PlayMan Poker' to parent set 'Jack Potten's Poker (set 1)' and clone (set 2). Changed 'Jack Potten's Poker (bootleg)' and 'Jack Potten's Poker (bootleg2)' from clones of 'PlayMan Poker' to clones 'Jack Potten's Poker (set 3)' and '(set 4)'. Renamed (goldnpkc) to (pottnpkr), (jokerpkr) to (potnpkra), (pottnpkb) to (potnpkrb) and (pottnpkr) to (potnpkrc). Rewrote pmpoker.c driver (first part) [Roberto Fresca, Grull Osgo]: Added discrete sound support to Potten's Poker hardware games based on PCB analysis. Added discrete circuitry diagram. Adjusted the CPU adressing to 14 bits for pottnpkr hardware. Rewrote all the ROM loads based on these changes. Defined MASTER Xtal & CPU clock. Fixed the visible area based on M6845 registers. Improved the lamps layouts to be more realistic. Renamed/cleaned all sets based on code/hardware analysis. Added intensity bit to the color system. Rewrote the graphics & color decode system based on schematics. No more patched codes. Changed the char gfx bank structure and rom load according to the new routines. Adjusted the amount of color codes and PROM region size accordingly. Updated all notes. Fixed main and gfx1 rom loading. Added Discrete sound. Changed visible area to 248x232.

- 0.115: Added dipswitches 'Jacks or Better', 'Royal Flush Value' and 'Payout Mode' to clone Joker-Poker. Added dipswitches 'Ace or Better' and 'Payout Mode' to clone Jack Potten's Poker.

- 0.108u5: Roberto Fresca added 'Joker Poker' (Golden Poker version without 'double-up') and 'Jack Potten's Poker' (same as Joker Poker, but with 'Aces or better' instead of jacks).
