Commodore 64 emulator. Get it HERE

13 August 2009 v1.0.5.27

========================

1) Added general option to enable/disable opposing joystick directions.

 

2) Speed optimisation to the CPU, CIA and VIC. The emulation is noticeable faster

on lines with no DMA fetches and no IRQs

 

3) Bug fix to the reverse keyboard matrix. Was broken for years!

 

4) Accurate emulation of the $DD00 VIC bank switch bug.

 

Unless something is majorly broken, the next release will include the long awaited debugger. Work on the debugger is now in progress.

- You can save the disassembled machine codes in two formats:

* a text format ".TXT" with full infos.

* an ASM2 compatible format ".ASM".

Just add ".TXT" or ".ASM" at the end of file name.

- In the ASM2 window, all lines will be trimmed to avoid to put comments in the text REM.

- "Crush" is gone, sorry !

- To install Windows links to VB81 XuR, launch "Setup_Programs_menu_links.js" placed in the "Icons" directory.

Link TXT, BAS, WAVs,Z81, P, 81, T81 and TZX. Most of files will be lauched and run in Vb81 XuR.

Hanafuda games to use them. Like for Mahjong games, keys A->H are used.

"Yes" is mapped to M, "No" is mapped to N. [Fabio Priuli]

implemented flip y. [Angelo Salese]

 

DIP switch cleanups in gberet, mainevt, ninjakd2, and taito_z.

[kanikani]

 

Added GAME_IMPERFECT_SOUND flag to all sets that use external samples

which were not already flagged for sound. Flagged Speed Freak

(speedfrk) as GAME_SUPPORTED_SAVE to match the rest of the driver.

[Tafoid]

 

SNES video updates: [Fabio Priuli]

* re-enabled video debug functionalities in debug build (to toggle

background layers)

* added proper priority tables for various bg/obj layers

* largely simplified tile and line drawing routines, and fixed small

bits here and there

* further simplification of tile drawing routines

* added palette index to 8bpp tiles (correct color_shift still unsure,

though)

* reworked video drawing routine to simplify the various graphic

mode drawing and to allow proper implementation of priority orders

(especially bg3 priority bit and mode 7 priority order)

* improved mode 7 extbg (still missing mosaic)

* added some more debugging options

* improved Mode 7 math precision (but still some issues remain) and

added a few elements to PPU struct

* implemented Mosaic in Mode 7

* merged OAM functions

* added a few elements to PPU struct (this might be handy if we ever

come to convert SNES PPU to a device)

* fixed Mode 7 shared scrolling/matrix registers

* slightly optimized Mode 7 math (by using Anomie's recursive

formula)

* moved some more register contents to PPU struct

* added PPU1/PPU2 Open Bus support, STAT77/STAT78 registers should be

more accurate (even if still not perfect)

* simplified window masking code and moved some more regs to PPU

struct

 

More NES work: [Robert Bohms]

* Fixed bug in nes_apu that caused errors reading $4015

* Added length counter status bits to $4015

* Fixed 4-screen mirroring (PPU regression)

* Fixed cham24

* Improved Sprite Overflow emulation of NES PPU (this fixes the first

of blargg's Sprite Overflow tests)

 

Added remaining PCB "U" locations to roms that didn't have for

G-Stream G2020. [brian Troha]

 

Atomiswave updates: [R. Belmont, Cah4e3]

- Emulate AW ROM board (different from Naomi)

 

Fixed buggy breakpoints in the g65816 cpu core. [Angelo Salese]

 

Fixed Atomiswave COIN ERROR. [Wind]

 

n8080 update [Team Japump!!!]

- corrected ROM names for Space Fever and SF High Splitter

- renamed spacefeva to spacefevo2

- Moved discrete sound related pieces such as initialization into

audio/galaxian.h

- Split some memory maps into sound related and not sound related

parts.

- Added possibility in discrete.h to select hardware (galaxian/moon

cresta) at compile time. This leads to slightly different volume

levels. Hit sound (explosion) has been hacked to increase volume.

Currently, we can not accurately model the switch/opamp filter

circuit.

- Rewrote timer code so that the pitch timer is only used when it

produces audible results.

 

Cojag/jaguar video updates (primarily for MESS) [Robbbert]

* Added variable pixel width.

* Fixed display of screens wider than 360 pixels.

set, added mcu support. [robiza]

 

Redumped bingor2 program roms [Klaus Sommers]

relabeled it a superg hack. Also the dipswitch setting for the Taito

license was the same as superg so I eliminated one. [brian Troha]

 

Improved speaker-toggle emulation with alias filter.

[Anders Hallstrom]

 

NES: Fixed bank switching in multigm3 (broken due to a mistake of

mine when including original Rob Bohms' code). The game still refuses

Added redumped gfx rom on Shogun Warrior [Guru]

 

Updated romload.c and validity.c to not rely on global variables.

[Atari Ace]

 

Corrected resistor values in Cliff Hanger discrete sound based on

actual PCB values. [Ruben Panossian]

 

Removed DAA tables from the 8085 and Z180 implementations in favor of

just computing the values. Also fixed code in 8085 to prevent

accidental multiple reads due to macro overuse. [hap]

 

Added game time and coinage DIP switches to Space Walk, along with

service mode and test. Also added support for the 2nd controller and

coin counter. Removed GAME_NOT_WORKING as it is working fine. Added

color overlay based on photo. [hap]
