NOTE: This requires 'non merged' type roms, with all files related to
the game in a single zip file, ares does NOT resolve parent/child
relationships between roms.
This emulates the ZX Spectrum 48k and 128k models and should be fairly accurate
although imperfect; it is considered experimental for now. Save States are not
fully implemented, you may wish to avoid using them for this core.
No controller interface is currently exposed, meaning games must be played with
the keyboard at this time. It is planned to support the Kempston interface,
while supported by the underlying core, the UI interface for attaching expansion
port devices has not yet been implemented.
You must map a "Keyboard Capture" hotkey to allow ares to emulate the keyboard.
Ares maps most ZX Spectrum keys 1:1 with the same key on the host keyboard.
CAPS SHIFT is mapped to Left Shift, and Symbol shift is mapped to Left Control.
For special characters, it may be beneficial to look up the ZX Spectrum
keyboard layout. For the 48K it is necessary, as BASIC uses hot keys
rather than typed commands, for example, to load a game on the 48k,you must
type `J <symbol shift> PP` and then hit enter, which results in `LOAD ""`
being entered on the screen.
For the ZX Spectrum 128k, you can just use the Tape Loader menu option.
The emulator only implements support for raw WAV dumps right now; this is
because the TZX format is over-complicated, and I did wish to implement it at
this time.
There are many tools available for converting TZX to WAV, for all platforms,
so this isn't really seen as a blocking issue.
Enable these warnings in nall so they apply to all of ares and annotate
legitimate fallthrough with C++17 standard [[fallthrough]] attribute.
This type of mistake is just too easy to make.
Add support for American Video Entertainment's NINA-001 board which was
used only by the unlicensed NES port of Impossible Mission II developed
by Novotrade.
iNES mapper 34 is assigned to two unrelated boards, so detection must
rely on the NES 2.0 header or use the CHR ROM size as a heuristic.
This change makes it possible to build ares using Clang without
MinGW-w64. All that is required is a copy of Visual Studio (or Build
Tools for Visual Studio) and Clang (also available through the VS
installer) along with GNU Make.
To build, just open an x64 Native Tools command prompt and run
`make compiler=clang++` as usual.
Begin the process of splitting nall into separate translation units.
It can now be used in two ways:
1) as a header-only library by defining NALL_HEADER_ONLY
2) by compiling nall/nall.cpp
sourcery has been updated to demonstrate the header-only use and
everything else now builds nall.cpp.
So far the only things moved into .cpp files are implementations that
call Windows APIs. This allows most of ares to build without including
windows.h and enables the removal of the abomination that was
windows/guard.hpp. The things that actually need windows.h (hiro, ruby)
must avoid using names reserved by Windows headers, but the rest of ares
is free to use names like "far", "boolean", and "interface" with
reckless abandon.
This work is done in preparation for building against MSVC and Windows
SDK headers/libraries an an alternative to MinGW-w64.
- Detect RTC with MBC30 mapper (Pocket Monsters - Crystal Version)
- Read current time before saving it to disk, not after
- Don't clear RTC in power()
mia cannot save a file when the manifest size is zero.
instead, use the largest known eeprom size + 1 as a default.
The +1 signifies that we should auto-detect the real size of the eeprom
and the large size makes sure mia creates a file on disk large enough.
For games without a database entry, the eeprom size be larger on disk
than is actually used, but it's better than completely broken saves.
Note that even with this, some games will require database entries,
but most should work now.
Following the precedent set by the SFC performance PPU, override the
timing of the PCE performance VDP for a handful of problematic games.
All of these games already work fine with the accuracy VDP (enabled with
the "pixel accuracy mode" video setting) which does not and never will
contain contain game specific logic.
Affected games:
- Kore ga Pro Yakyuu '89
- Kore ga Pro Yakyuu '90
- TV Sports Baseball
- TV Sports Football
- TV Sports Hockey
- Valkyrie no Densetsu
- Victory Run
This commit introduces preliminary Atari 2600 emulation.
In the current state, many games are working but with the following caveats
1. Only a small subset of mappers are supported
2. The TIA isn't cycle accurate yet; many games have rendering and/or collision issues.
There is currently little-to-no reason to use this over other Atari 2600 emulators at this time,
but the goal is to eventually have cycle-accurate atari emulation.
To get clean makefile targets working robustly under a Windows command
prompt, allow the entire contents of obj/out directories to be deleted.
They are now recreated by the build as needed.
Replace uses of Bourne shell commands (cp, mkdir) with shell-agnostic
versions that work from a Windows command prompt. Some Bourne shell
commands still remain in macOS and Linux specific makefile lines.
This is because C-BIOS has significant compatibility issues, including
the ability to boot any software that uses BASIC.
The MSX2 emulation is still too preliminary to be able to boot the
official bios, so msx2 will continue to use C-BIOS for the time being.
Nintendo 64 homebrew community is standardizing on a convention to
declare the save memory type as a header flag. This convention has been
first introduced by EverDrive 64 as a way to handle games not present
in their DB, but it's been since adopted by libdragon as well.
With this commit, Ares will automatically configure the correct savetype
for homebrew ROMs using the special header flag.
* Allow MIA to declare address for mapping (typically from ROM header)
rather than hardcoding 0x200000.
* Autoenable SRAM if the ROM size is smaller. Also make the ramEnable
I/O conditional to the same layout.
* Add MIA entries for NBA Live 98, NHL 96 and NHL 98, which have a 8-bit
SRAM not declared in the header.
The Korean release of Tiny Toon Adventures specifies its region with a
'K' and, like several other Korean releases, is region locked to
Japanese consoles. It may be the only one with a 'K' specifier, though.
Games tested so far. Two new not working games discovered:
- Aladdin (Europe): Hangs after starting game
- Wizards & Warriors (Europe): Graphicals glitches on HUD, severe slowdowns. PAL timing related?
Instead of just reading the first file from a zip archive, prefer files
that match known rom extensions. Extra files such as readmes should not
interfere with the loading of the game.
Jeopardy! only supports up to 3 players, and if four controllers are
plugged in when the game starts, it performs an out of bounds array
access that breaks further input logic. The only workaround is to unplug
a controller and reset the system. To make this game work well in ares
out of the box, we should connect no more than 3 controllers by default.
I opted to put a check specifically in desktop-ui because this is
fundamentally a mismatch between a specific game and a design choice (to
default to 4 controllers) in the desktop-ui frontend. It didn't feel
right to add a dedicated attribute to mia that did not describe a
feature of the cartridge itself and would not be generally applicable
other games (unlike rumble and memory pak support).
This change also brings the rumble and memory pak attributes in line
with the implementation of boolean attributes for other systems. There
is no functional change, though it will affect generated manifests if
they are/were persisted to disk.
This removes the special casing for Sonic & Knuckles, treating it as a standard rom.
While not strictly correct from an accuracy/real world point of view, all existing
emulators and rom dumps assume the emulator will treat it as a single cart.
