Improved the IGS017 based games:
- iqblocka: bypassed the protection, emulated the video hardware, inputs and sound. - tjsb: it now boots and has partially decrypted graphics. [Luca Elia]

/***************************************************************************
|
||||
|
||||
-= IGS017 Based Hardware =-
|
||||
|
||||
driver by Pierpaolo Prazzoli, Luca Elia (l.elia@tin.it)
|
||||
|
||||
CPU: Z180 (HD64180)
|
||||
GFX: IGS017 (2 tilemaps, variable size sprites, protection)
|
||||
SOUND: M6295, YM2413
|
||||
OTHER: IGS025
|
||||
|
||||
To Do:
|
||||
|
||||
- Protection emulation, instead of patching the roms.
|
||||
- tjsb: finish sprites decryption (data lines scrambling), protection, inputs.
|
||||
- iqblocka: NVRAM.
|
||||
- iqblockf: protection.
|
||||
|
||||
Notes:
|
||||
|
||||
- iqblocka: keep start or test pressed during boot to enter test mode A or B.
