2014-02-08Initial GDB remote debugging support. Lacks some features, but breakpoints ↵Mike Pavone
and basic inspection of registers and memory work.
2014-02-07Implement per-channel wave logging and primitive looping support in vgm player.Michael Pavone
2014-02-07Properly clamp envelope value to zero when it overflows during the attack ↵Michael Pavone
phase. This fixes a number of instruments that sounded rather wrong as well as the missing melody line from Mushroom Hill Zone in Sonic and Knuckles
2014-02-07Increment sample pointer after reading a sample in VGM playerMichael Pavone
2014-02-06Add support for VGM 1.50 PCM data blocksMichael Pavone
2014-02-06Add a zp command to the 68K debugger to allow printing Z80 registers while ↵Michael Pavone
in the 68K debugger
2014-02-06Fix accidental use of the conditional jump instruction jp instead of jmpMichael Pavone
2014-02-03Initial attempt at emulating extended bank area access delays when 68K bus ↵Michael Pavone
is busy with VDP stuff. Also emulate the extra delay on the second access of a word-wide read to the bank area. Needs work as it seems to break stuff.
2014-01-28Add 3 wait states to Z80 access to bank area since that seems to be roughly ↵Michael Pavone
the average in normal usage
2014-01-27Fix timing of certain ld and jp instructions in the Z80 coreMichael Pavone
2014-01-06The local clone on my laptop got messed up and some changes had not been ↵Michael Pavone
pushed. This commit represents the status of the working copy from that clone. It unfortunately contains some changes that I did not intend to commit yet, but this seems like the best option at the moment.

2013-10-31Small optimization for H40 modeMike Pavone
2013-10-29Fix allocation and memset size for field buffers when using OpenGLMike Pavone

2013-10-29MergeMike Pavone
2013-10-28Pull shader file names from config file.Mike Pavone
2013-10-28Move shader files to their own directory. Read shaders from ↵Mike Pavone
/.config/blastem/shaders or from path_to_exe/shaders instead of the current working directory.
2013-10-28Extract function to determine executable directory from load_config so it ↵Mike Pavone
can be used elsewhere
2013-10-28Allow OpenGL support to be disabled at compile time. Move generic utility ↵Mike Pavone
functions out of config.c

2013-10-07Initial implementation of sprite overflow and sprite collision status ↵Mike Pavone
register flags
2013-10-04Add support for UI bindings on gamepad buttons and dpadsMike Pavone
2013-10-03Add an FPS counter to the title barMike Pavone
2013-10-03Follow amd64 ABI stack alignment requirements in places it matters so we can ↵Mike Pavone
call sprintf with floating point arguments without crashing
2013-10-03Add support for test instruction to x86 generator libraryMike Pavone
2013-10-01Implement turbo/slow motion feature that overclocks or underclocks the ↵Mike Pavone
entire system at the push of a button
2013-09-18Theoretically more correct timing of Z80 bus requestMike Pavone
2013-09-17Set VBLANK flag in status register when display is disabledMike Pavone
2013-09-17Implement HV counter latchMike Pavone
2013-09-17Implement funny behavior for DMA fill to CRAM and VSRAM. Return VSRAM ↵Mike Pavone
address 0 for reads to VSRAM at >= 40
2013-09-17Fix DMA fill so that it does not cause observable changes to the FIFO. Get ↵Mike Pavone
DMA copy mostly correct from an observable ffect perspective. DMA copy probably does not reflect internal implementation still given that evidence seems to suggest no FIFO usage at all.
2013-09-16Partial fix for DMA copyMike Pavone
2013-09-15Clear the low 2 bits of CD when a register is written toMike Pavone
2013-09-15Don't allow register writes to regs above when in Mode 4Mike Pavone
2013-09-15Remove read pending stuff, that had been added in an attempt to fix ↵Mike Pavone
CRAM/VSRAM undefined bit results. Set number of bits actually saved in VSRAM to 11
2013-09-15Implement undocumented 8-bit VRAM readMike Pavone
2013-09-15Fix VSRAM readsMike Pavone
2013-09-15Implement FIFO as a ring buffer so the behavior of reads from invalid CRAM ↵Mike Pavone
and VSRAM bits can be implemented properly
2013-09-13Properly delay 68K on VDP reads. Dummy VDP test port implementation. Initial ↵Mike Pavone
stab at handling undefined bits of VSRAM and CRAM.
2013-09-11Fix argument handling so that the rom filename does not need to be specified ↵Mike Pavone
first
