Up Scope

0.105u3 [Mariusz Wojcieszek, Tomasz Slanina, Aaron Giles]


- 0.113u2: Changed VSync to 59.997000 Hz.

- 0.111u6: Ernesto Corvi fixed the data fetch and scrolling calculation for almost all video modes in the Amiga driver.

- 0.111u5: Nathan Woods updated the Amiga video driver to use the new BITMAP_ADDR* macros instead of using the line[] array.

- 0.111u2: Amiga core system updates [Ernesto Corvi]: Updated 6526/8520 CIA to be able to set the value of the SP pin. This is needed to emulate the Amiga keyboard. Updated the custom chips emulation to delay for about 24 cycles the issuing of interrupts after a write to INTENA or INTREQ. Fixed a bug where if INTREQ got cleared programatically, it would 'forget' about pending CIA interrupts, causing the CIA to stop sending further interrupts. Fixed the interrupt delay logic. Now it properly delays firing the irqs, not the masking/disabling. Fixed return value for unused/invalid custom registers reads. Added Denise ID custom register to properly identify OCS, ECS and AGA. Added reset to custom, autoconfig and cia when a RESET opcode is found. Resetting the custom chips will now clear INTENA, preventing further interrupts. Fixed a bug in the RBF interrupt request code check. Fixed a bug on the 6526/8520 CIA that prevented chained counters from working. Added support for the 'blitter-nasty' bit on the blitter. Fixes many games that displayed wrong graphics.

- 0.110u5: Aaron Giles added serial in/out support to the Amiga hardware. Added hooks for output pins and light pen positioning. Also fixed the horrible static at startup in the debug build.

- 0.105u3: Added Up Scope. More Amiga cleanups [Aaron Giles]: Fixed dual playfield mode. Rewrote blitter code. Changed Arcadia boot loading to use ROMtags instead of autoconfig. Swapped Kickstart 1.2 in for Arcadia BIOS. Nathan Woods refactored the 8530 CIA code from the Amiga into a separate module and made it support both the 6526 and 8530 variants.

- 1st March 2005: Mariusz Wojcieszek - Finished a driver for Up Scope (Grand Products 1986) based on Commodore Amiga hardware.
