7 Extract this archive to a directory of your choosing. If you wish to change the |
| 1066 | 8 configuration settings, copy default.cfg to $HOME/.config/blastem/blastem.cfg |
| 9 and modify the copy. If you are on Windows, the config file should be placed in | |
| 10 %localappdata%\blastem. You may also whish to add the blastem directory to your | |
| 11 PATH environment variable. | |
| 12 | |
| 13 NOTE: Prior to version 0.4.1, BlastEm was still using Unixy locations for config | |
| 14 and save files. If you're upgrading from a previous version on Windows, you will | |
| 15 need to move them manually. For config files, the relevant paths are in the | |
| 16 previous paragraph. For save files, move all the directories found in | |
| 17 %userprofile%\.local\share\blastem to %localappdata%\blastem | |

| 1013 | 22 This version of BlastEm has an experimental GUI that is implemented as a Genesis |
| 23 ROM running inside the emulator. This UI can be operated with either a mouse or | |
| 24 the first emulated gamepad. By default, both the keyboard and the first game | |
| 25 controller are mapped to said gamepad. For more information on bindings see the | |
| 26 Bindings section. | |

| 28 Some operations are currently only supported through the command line. To get a | |

| 134 The mice subsection is used to map mice to emulated Mega/Sega mice. The default | |
| 135 configuration maps both the first and second host mice to the first emulated | |
| 136 mouse. This should not need modification for most users. | |
| 137 | |
| 138 One special mapping deserves a mention. By default, the 'r' key is mapped to | |
| 139 ui.release_mouse. When operating in windowed mode the mouse has a capture | |
| 140 behavior. Mouse events are ignored until you click in the window. The mouse | |
| 141 will then be "captured" and the cursor will be both made invisible and locked | |
| 142 to the window. The ui.release_mouse binding releases the mouse so it can be | |
| 143 used normally. | |

203 shader and a "subtle" crt shader. If you write your own shaders, place them in |
| 1013 | 204 $HOME/.config/blastem/shaders and then specify the basename of the new shader |
| 205 files in the "vertex_shader" and "fragment_shader" config options. Note that | |

| 208 "scanlines" controls whether there is any emulation of the gaps between display | |
| 209 lines that are present when driving a CRT television with a 240p signal. This | |
| 210 emulation is very basic at the moment so this option is off by default. | |
| 211 | |
| 212 "vsync" controls whether the drawing of frames is synchronized to the monitor | |
| 213 refresh rate. Valid values for this setting are "off", "on" and "tear". The | |
| 214 latter will attempt to use the "late tear" option if it's available and normal | |
| 215 vsync otherwise. Currently it's recommended to leave this at the default of | |
| 216 "off" as BlastEm synchronizes to audio and does not yet have the necessary code | |
| 217 to fully handle conflicts between the audio rate and monitor refresh rate. | |
| 218 Additionally, the "turbo" feature does not function properly with vsync | |
| 219 enabled. These issues will be addressed in a future release. If you wish to use | |
| 220 vsync, please see the VSync section at the bottom of the README. | |

| 468 | 263 Audio |
| 264 ----- | |
| 265 | |
| 1014 | 266 The audio section contains settings that affect the audio output of BlastEm. |
| 1013 | 267 |
| 268 "rate" selects the preferred sample rate for audio output. Your operating | |
| 269 system may not accept this value in which case a different rate will be chosen. | |
| 270 This should generally be either the native sample rate of your sound card or an | |
| 271 integral divisor of it. Most modern sound cards have a native output rate that | |
| 272 is a multiple of 48000 Hz so the default setting should work well for most users. | |
| 273 | |
| 274 "buffer size" controls how large of a buffer uses for audio data. Smaller values | |
| 275 will reduce latency, but too small of a value can lead to dropouts. 512 works | |
| 276 well for me, but a higher or lower value may be more appropriate for your system. | |
| 277 | |
| 278 "lowpass_cutoff" controls the cutoff, or knee, frequency of the RC-style | |
| 279 low-pass filter. The default value of 3390 Hz is supposedly what is present in | |
| 280 at least some Genesis/Megadrive models. Other models reportedly use an even | |
| 281 lower value. | |
| 468 | 282 |
| 1014 | 283 Clocks |
| 284 ------ | |
| 285 | |
| 286 The clocks section contains settings that affect how fast things run. | |
| 287 | |
| 288 "m68k_divider" describes the relationsip between the master clock (which is | |
| 289 53693175 Hz for NTSC mode and 53203395 Hz for PAL mode). The default value of 7 | |
| 290 matches the real hardware. Set this to a lower number to overclock the 68000 | |
| 291 and set it to a higher number to underclock it. | |
| 292 | |
| 293 "max_cycles" controls how often the system is forced to synchronize all | |
| 294 hardware. BlastEm generally uses a sync on demand approach to synchronizing | |
| 295 components in the system. This can provide perfect synchronization for most | |
| 296 components, but since the Z80 can steal cycles from the 68000 at unpredictable | |
| 297 times 68000/Z80 synchronization is imperfect. The default value of 3420 | |
| 298 corresponds to the number of master clock cycles per line. Larger numbers may | |
| 299 produce a modest performance improvement whereas smaller numbers will improve | |
| 300 68000/Z80 synchronization. | |
| 301 | |
| 302 "speeds" controls the speed of the overall emulated console at different | |
| 303 presets. Preset 0 is the default speed and should normally be set to 100. The | |
| 304 other presets enable the slow/turbo mode functionality. | |

| 1014 | 367 "default_region" determines the console region that will be used when region |
| 368 detection fails and when there are multiple valid regions. The default of 'U' | |
| 369 specifies a 60Hz "foreign" console. | |
| 370 | |
| 468 | 371 Debugger |
| 372 -------- | |
| 373 | |
| 374 BlastEm has an integrated command-line debugger loosely based on GDB's | |
| 375 interface. The interface is very rough at the moment. Available commands in the | |
| 376 68K debugger are: | |
| 1066 | 377 b ADDRESS - Set a breakpoint at ADDRESS |
| 378 d BREAKPOINT - Delete a 68K breakpoint | |
| 379 co BREAKPOINT - Run a list of debugger commands each time | |
| 1014 | 380 BREAKPOINT is hit |
| 1066 | 381 a ADDRESS - Advance to address |
| 382 n - Advance to next instruction | |
| 383 o - Advance to next instruction ignoring branches to | |
| 384 lower addresses (good for breaking out of loops) | |
| 385 s - Advance to next instruction (follows bsr/jsr) | |
| 386 c - Continue | |
| 387 bt - Print a backtrace | |
| 388 p[/(x|X|d|c)] VALUE - Print a register or memory location | |
| 389 di[/(x|X|d|c)] VALUE - Print a register or memory location each time | |
| 390 a breakpoint is hit | |
| 391 vs - Print VDP sprite list | |
| 392 vr - Print VDP register info | |
| 393 zb ADDRESS - Set a Z80 breakpoint | |
| 394 zp[/(x|X|d|c)] VALUE - Display a Z80 value | |
| 395 q - Quit BlastEm | |
| 468 | 396 Available commands in the Z80 debugger are: |
| 1066 | 397 b ADDRESS - Set a breakpoint at ADDRESS |
| 398 de BREAKPOINT - Delete a Z80 breakpoint | |
| 399 a ADDRESS - Advance to address | |
| 400 n - Advance to next instruction | |
| 401 c - Continue | |
| 402 p[/(x|X|d|c)] VALUE - Print a register or memory location | |
| 403 di[/(x|X|d|c)] VALUE - Print a register or memory location each time | |
| 404 a breakpoint is hit | |
| 405 q - Quit BlastEm | |
| 468 | 406 |
| 407 The -d flag can be used to cause BlastEm to start in the debugger. | |
| 408 Alternatively, you can use the ui.enter_debugger action (mapped to the 'u' key | |
| 1014 | 409 by default) to enter the debugger while a game is running. To debug the menu |
| 410 ROM, use the -dm flag. | |
| 468 | 411 |
| 536 | 412 GDB Remote Debugging |
| 413 -------------------- | |
| 414 | |
| 415 In addition to the native debugger, BlastEm can also act as a GDB remote | |
| 416 debugging stub. To use this, you'll want to configure your Makefile to produce | |
| 417 both an ELF executable and a raw binary. Invoke an m68k-elf targeted gdb with | |
| 418 the ELF file. Once inside the gdb session, type: | |
| 419 | |
| 1066 | 420 target remote | BLASTEM_PATH/blastem ROM_FILE.bin -D |
| 536 | 421 |
| 422 where BLASTEM_PATH is the relative or absolute path to your BlastEm | |
| 423 installation and ROM_FILE.bin is the name of the raw binary for your program. | |
| 424 BlastEm will halt at the beginning of your program's entry point and return | |
| 425 control to GDB. This will allow you to set breakpoints before your code runs. | |

| 1013 | 448 VSync |
| 449 ----- | |
| 450 | |
| 1014 | 451 This section includes information about using VSync with BlastEm. As mentioned |
| 452 above, the code is currently designed to only sync to audio and has some issues | |
| 453 with VSync as a result. That said, if your computer is fast enough and you | |
| 454 don't care about turbo mode, it can generally made to work. | |
| 455 | |
| 456 The native refresh rate of an NTSC Genesis is approximately 59.92 Hz which is | |
| 457 probably not the native refresh rate of your monitor. Fortunately, it is | |
| 458 most likely lower than your refresh rate. As long as this is true, VSync will | |
| 459 generally work as long as your computer is fast enough to cope with the time | |
| 460 lost waiting for VSync and the audio buffer is large enough to not run out of | |
| 461 samples during that delay. Latency will suffer a bit and you'll get a doubled | |

462 frame every once and a while, but generally things will be fine. |
| 1014 | 463 |
| 464 If you enable VSync and you're getting audio dropouts, first try doubling the | |
| 465 audio buffer setting. If you still experience dropouts, it's possible your | |
| 466 computer is not fast enough or that your monitor's actual refresh rate is in | |
| 467 fact lower than that of the emualted console. Not much can be done about the | |
| 468 former (apart from disabling VSync), but the latter can be dealt with by | |
| 469 lowering the default speed slightly in the "clocks" section. | |
| 470 | |
| 471 A future release will support VSync in a less hacky fashion. | |

| 1066 | 473 Special Thanks |
| 474 -------------- | |
| 475 | |
| 476 My work has been made much easier by the contributions of those in the Genesis | |
| 477 community past and present. I'd like to thank the people below for their help. | |
| 478 | |
| 479 Nemesis - His work reverse engineering and documenting the VDP and | |
| 480 YM-2612 has saved me an immeasurable amount of time. I've | |
| 481 found both his sprite overflow test ROM and VDP FIFO | |
| 482 Testing ROM to be quite helpful. | |
| 483 | |
| 484 Charles MacDonald - While it hasn't been updated in a while, I still find his | |
| 485 VDP document to be my favorite reference. His Genesis | |
| 486 hardware document has also come in handy. | |
| 487 | |
| 488 Eke-Eke - Eke-Eke wrote a great document on the use of I2C EEPROM in | |
| 489 Genesis games and also left some useful very helpful | |
| 490 comments about problematic games in Genesis Plus GX | |
| 491 | |
| 492 Bart Trzynadlowski - His documents on the Genecyst save-state format and the | |
| 493 mapper used in Super Street Fighter 2 were definitely | |
| 494 appreciated. | |
| 495 | |
| 496 KanedaFR - Kaneda's SpritesMind forum is a great resource for the | |
| 497 Sega development community. | |
