Releases: Commnets/EMULATORS
C64 VICII border emulation
The VICII emulation is now as real VICII's!
Some measures to also speed up VICII emulation have been introduced.
The Spectrum emulation still in progress!
T64s, PRGs, and CRT formats working in C64
T64s, PRGs, and CRT formats working in C64.
The way the memory is managed is improved. Now many more games work.
The way the PLA assign the different zones of memory is also improved. Now the assignement is more accurate.
Some commands also of the Console are improved.
C64 VICII Sprites & Ultimax mode Ok, VIC20, CPlus4 and ZX81 emulations
The C64 draws much better the sprites and now games like H.E.R.O (from cartridge) that didn't work before.
Commands to draw the sprites and the characters from the memory have been created (at they are seen from VICII).
Commands to draw the structure of the memory have been also created.
The help files have been adapted in consequence.
The local console now check the right number of parameters in the commands CONNECTPER and DISCONECTPERS.
The T64 format is now accepted.
There might be a problem in the way the PLA set the configuration of the memory. Some games, specially the big ones but not all of them crashs when are loaded from T64 or PRG formats.
C64, VIC20, C264 and ZX81
In this release the 6500 and Z80 CPU are emulated.
On top of those emulations, simulation of the computers: C62, VIC, C264 series and Z80 are provided!
VIC20 Emulation works
VIC20 Emulation works even with different memory configurations.
The keyboard works.
The VIA chips are emulated with all functions (at least defined).
With first VIC20 version
The framework has been updated with the classes needed to emulate a VIC20.
Still far away from a real production version (on the VIC20 emulation I mean, not in the C64), but the VICI chip video is emulated and also the different configurations of memory.
Multicolor chart text mode sorted out
The multicolor mode has been sorted out...I think.
Also a minor mistake in the way the VICII interrupts were recognize (d019 register).
VICII Graphics & Sprites like Original
In this release the way that VICII draws graphics (managing mainly SCROLLY attribute and raster) is almost like it is described in this amaizing article: https://www.cebix.net/VIC-Article.txt.
Better Keyboard Emulation
Over the improvements done arounf VICII, this new realease adds significant changes in the way that the jeyboard and the joysticks are emulated.
Now much more games run!
C64 VICII much more real & CRT Filtering running
In this version, the main differences with the previous are:
1.- CRT Filtering working: And it can be activated or desactivated.
2.- VICII chip is much better emulated: The sprites info is read per raster line. The sprites 0 to 2 info is read at the end of the previous raster line, while the sprites 4 to 7 info is read at the beginning of the current raster line. When either the info of the graphics or the sprites is read the mainCPU is stopped for a couple of cycles as per original VICII works.
3.- The cartridge games have been clasified in 4 folders: The ones working perflectly, and the rest hacing some kind of issue (control, video or unknown).
4.- The very detailed debug info can be activated or desactivated even only for the interruptions. This feature allows to trace how they work very carefully.
