r36

283e99f

x16-emulator-r36 ("Berlin")

Main differences:

BREAKING CHANGES:

The host filesystem interface is now on device 8, also, device 8 is the default for LOAD and SAVE. So if you don't specify a device number, LOAD and SAVE behave as before. If an SD card is attached (-sdcard), the host filesystem interface is disabled, and the SD card is used instead.
GRAPH_init needs to be called with r0 = 0 for the r35 behavior.
GRAPH_get_char_size behaves differently for control characters. See documentation for details.

A lot of new APIs have been added:

sprites
console
memory

See the Programmer's Reference Guide for details on the new and changed APIs:

https://github.com/commanderx16/x16-docs

Emulator:

added VERA UART emulation (-uart-in, -uart-out)
correctly emulate missing SD card
moved host filesystem interface from device 1 to device 8, only available if no SD card is attached
require numeric argument for -test to auto-run test
fixed JMP (a,x) for 65c02
Fixed ESC as RUN/STOP [Ingo Hinterding]

ROM:

API Features
- added console API for text-based interfaces with proportional font and styles support: console_init, console_put_char, console_get_char
- added memory API:
  - memory_fill
  - memory_copy
  - memory_crc
  - memory_decompress (LZSA2)
- added sprite API: sprite_set_image, sprite_set_position
- renamed GRAPH_LL to FB (framebuffer)
- GRAPH_init takes an FB graphics driver as an argument
KERNAL features
- detect SD card on TALK and LISTEN, properly fall back to serial
- joystick scanning is done automatically in VBLANK IRQ; no need to call it manually any more
- added VERA UART driver (device 2)
- bank 1 is now the default after startup; KERNAL won't touch it
- sprites and layer 0 are cleared on RESET
- changed F5 to LOAD":* (filename required for IEEE devices)
- GRAPH_move_rect supports overlapping [gaekwad]
BASIC
- default LOAD/SAVE device is now 8
- added RESET statement [Ingo Hinterding]
- added CLS statement [Ingo Hinterding]
CHARSET
- fixed capital Ö [Ingo Hinterding]

8dc5dcf

x16-emulator-r35

Main differences:

BREAKING CHANGES:

The zero page and $0200+ layouts have changed once again. From now on, they will not remain stable. New KERNAL APIs will be added to replace direct variable access.
RAM bank 0 ($A000-$BFFF) is now used for KERNAL variables. Applications should use banks 1 and above.

A lot of new APIs were added to the KERNAL. You can now draw to the 320x200@256c screen from assembly without touching VERA registers. The graphics API can also draw proportional text (using the built-in font, or a user-supplied font in GEOS format), and supports most PETSCII control codes.

The Programmer's Reference Guide describes all new KERNAL calls:

https://github.com/commanderx16/x16-docs

Known Issues:
The built-in monitor has several regressions.

Emulator:

video optimization [Neil Forbes-Richardson]
added '-geos' to launch GEOS on startup
added '-test' to launch (graphics) unit test on startup
debugger
- switch viewed RAM/ROM bank with numpad + and numpad - [Kobrasadetin]
- optimized character printing [Kobrasadetin]
trace mode:
- prepend ROM bank to address in trace
- also prints 16 bit virtual regs (graph/GEOS)
fixes
- initialize memory to 0 [Kobrasadetin]
- fixed SYS hex argument
- disabled "buffer full, skipping" and SD card debug text, it was too noisy

ROM:

API Fetures
- new KERNAL API: low-level and high-level 320x200@256c bitmap graphics
- new KERNAL API: get mouse state
- new KERNAL API: get joystick state
- new KERNAL API: get/set date and time (old RDTIM call is now a 24 bit timer)
- new floating point API, jump table at $FC00 on ROM bank 4 (BASIC)
KERNAL Features
- invert fg/bg color control code (Ctrl+A) [Daniel Mecklenburg Jr]
BASIC
- added COLOR <fg, bg> statement to set text color
- added JOY(n) function (arg 1 for joy1, arg 2 for joy2)
- added TEST statement to start graphics API unit test
- CHAR statement supports PETSCII control codes (instead of GEOS control codes), including color codes
misc
- KERNAL variables for keyboard/mouse/clock drivers were moved from $0200-$02FF to RAM bank #0
- $8F (set PETSCII-UC even if ISO) printed first after reset [Mikael O. Bonnier]
bug fixes:
- got rid of $2c partial instruction skip [Joshua Scholar]
- fixed TI/TI$
- fixed CDBOS infinite loop
- zp address 0 is no longer overwritten by mouse code
- mouse scanning is disabled if mouse is off
- VERA state is correctly saved/restored by IRQ code

- ($02-$52 are used if using BASIC graphics commands)
- $80-$A3 used by KERNAL and DOS
- $A4-$A8 reserved for KERNAL/DOS/BASIC
- $A9-$FF used by BASIC

- PSET <x>, <y>, <color>
- LINE <x1>, <y1>, <x2>, <y2>, <color>

f7d6862

x16-emulator-r33

Main differences:

BREAKING CHANGE: The contents of the ROM banks have changed: KERNAL: 0, KEYBD: 1, CBDOS: 2, GEOS: 3, BASIC: 4.

Emulator:

significant performance optimizations
VERA
- enabled all 128 sprites
- correct sprite zdepth
- support for raster IRQs
SDL controller support using -joy1 and -joy2 [John J Bliss]
65C02 BSD fixes [Norman B. Lancaster]
feature parity with new LOAD/VLOAD features [John-Paul Gignac]
default RAM and ROM banks are now 0, matching the hardware
GIF recording can now be controlled from inside the machine [Randall Bohn]
Debugging
- Major enhancements to the debugger [kktos]
- -echo will now encode non-printable characters like this: \X93 for CHR$(93), -bas as well as pasting accepts this convention again
- -echo raw for the original behavior
- -echo iso to for correct character encoding in ISO mode
- -ram to specify RAM size; now defaults to 512

ROM:

BASIC
- additional LOAD syntax to load to a specific address LOAD [filename[,device[,bank,address]]]
- LOAD into banked RAM will auto-wrap into successive banks
- LOAD allows trailing gargabe; great to just type "LOAD" into a directory line [John-Paul Gignac]
- new BASIC statement: VLOAD to load into video RAM: VLOAD [filename[,device[,bank,address]]] [John-Paul Gignac]
- complete jump table bridge
KERNAL: memory size detection
KERNAL: faster IRQ entry
GEOS: converted graphics library to VERA 320x200@256c

Known Issues:

Emulator: LOAD"$ (and LOAD"$",1) will show host uppercase filenames as garbage. Use Ctrl+o to switch to ISO mode for a workaround.
Shift+AltGr keyboard combinations don't work

9afe3a9

x16-emulator-r32

Main differences:

BREAKING CHANGE: ROM banking now follows the updated specification: All of $C000-$FFFF is bankable ROM (8 banks, 16 KB each, for a total of 128 KB), and there is no more fixed ROM. Machine language programs started with "SYS" will have the BASIC ROM mapped at $C000-$FFFF and have to write #7 to $9F61 to switch to the KERNAL ROM. The KERNAL API $FF81+ is supported both from the BASIC ROM and the KERNAL ROM, but it's faster from the KERNAL ROM, and the extended API is only available from the KERNAL ROM.

Emulator:

correct ROM banking
VERA emulation optimizations [Stephen Horn]
added -dump option to allow writing RAM, CPU state or VERA state to disk [Nils Hasenbanck]
added -quality option to change scaling algorithm; now defaults to "best" [Maurizio Porrato]
output of -echo can now be fed into UNIX pipes [Anonymous Maarten]
relative speed of emulator is shown in the title if host can't keep up [Rien]
fix: 6502 BCD arithmetic [Rien]
fix: colors (white is now white) [Rien]
fix: sprite flipping [jjbliss]

ROM:

correct ROM banking:
- BASIC and KERNAL now live on separate 16 KB banks ($C000-$FFFF)
- BASIC "PEEK" will always access KERNAL ROM
- BASIC "SYS" will have BASIC ROM enabled
added GEOS statement
added OLD statement to recover deleted BASIC program after NEW or RESET
removed software RS-232, will be replaced by VERA UART later
Full ISO mode support in Monitor

Known Issues:

F4 to switch between 40 and 80 column has no effect
Emulator: LOAD"$ (and LOAD"$",1) will show host uppercase filenames as garbage. Use Ctrl+o to switch to ISO mode for a workaround.
Shift+AltGr keyboard combinations don't work
