Program:
- Support for Green Beret, with partial sound (probably inaccurate).
Colors are terrible. If you can see what you are doing, it's playable (but
should it be this fast? I find it very hard)
- Richard Davies and Brad Oliver provided drivers for the so-called "Sega"
version of Jump Bug (it's actually a bootleg with the protection checks
removed). The driver supports sound.
- Added joystick support to Vanguard.
- Support for Fantasy on the Nibbler driver. There are several problems, it's
not playable.
- Thanks to Mike Coates and Peter Clare, Carnival now has colors.
- Stefano Mozzi provided a much better palette for Mario Bros.
- Matthew Hillmer submitted a new palette for Donkey Kong 3. It is not
intended to be correct, but at least it gets rid of the annoying
checkerboard effect.
- Tormod Tjaberg provided updated Space Invaders (+clones) drivers which
support sound. They use samples, derived from Michael Strutts' emulator.
- Support for Fantazia (bootleg version of Moon Cresta)
- Fixed a couple of remaining graphic glitches in the Wizard of Wor driver.
- Various fixes to Burger Time:
- Fixed CPU clock speed to avoid slowdowns on fourth level.
- It's much faster on a 486.
- Sprites no longer "stick" on the screen on a level change.
- Fixed a bug in high score save.
DELETE BTIME\BTIME.HI, OTHERWISE THE HIGH SCORE TABLE WILL BE CORRUPTED
- Marc Lafontaine provided a Venture driver. It is partially playable,
sprites are wrong.
On startup, keep 1 or 2 pressed to proceed.
Source:
- I wrote some general purpose routines to simplify interface with the AY8910.
They are in 8910intf.c. See the existing drivers for usage examples.
- To solve the problem with garbled text messages in Time Pilot, modified the
GameDriver structure replacing letters_start and numbers_start with the
array charset[36].
- I finally took the time to change Z80.h/M6502.h to make them work together.
This allowed me to remove some kludges in cpuintrf.c. I also added some new
functions, which can be used regardless of the CPU type: cpu_getpc(),
cpu_geticount(), cpu_seticount().
- Fixed a couple of bugs in M6502 BCD arithmetic. One of them was causing the
pepper counter in Burger Time to behave strangely.
- Brad Oliver modified pokey.c and pokey.h to make them more portable.
