Emulicious to nowy, przynajmniej dla mnie, projekt multiemulatora systemów SEGA (master system, game gear) i Nintendo (Gameboy BW/Color) napisany w Javie. Celem emulatora jest dołączenie do aplikacji typu cycle exact, jednak po drodze do tego multiemulatora dodano parę ciekawych narzędzi - podgląd spritów, kafelków i całkiem użyteczny debugger.
It comes with serveral new features and some improvements to existing tools.
BIOS files for all supported systems can be selected now. For casual users this can help to improve the authenticity of the emulated system. But also developers can benefit from it because they can test if their rom will be rejected by the BIOS. Additionally, the state of the system after the BIOS will be faithfully reproduced. Appropriate BIOS files can be found on the web.
The Master Everdrive and the Everdrive GG can be emulated now. This feature as well can help to improve the authenticity of the emulated system. Developers can test if their rom is compatible with an Everdrive and also the state of the system after the Everdrive will be faithfully reproduced. To enable Everdrive emulation you need an Everdrive OS file. These can be found on the official website of the Everdrive. You can select a 1bpp font to use with the Everdrive but you can also let Emulicious derive a 1bpp font from the system font. Recent versions of the Everdrive OS come with their own font. They ignore the selected font.
The Memory Editor got expanded by a context menu and its interaction with the Debugger has been improved. Table files can now be manually selected in the Memory Editor and symbol files can now be manually selected in the Debugger. Furthermore, the Memory Editor now supports multi-selection and copy&paste. The Coverage Analyzer also got expanded by a context menu. It allows to exclude selected addresses from the analysis or to reset the collected data for selected addresses.

- Fixed an issue with Remote Debugging that could disconnect the remote debugger on launch if a ROM was already loaded
This update fixes several issues. For example, some users (mainly Linux users) have reported that the initial sizes of the viewers were too small. So when they first opened them, they weren’t usable until they resized them. This issues should be fixed now.
Furthermore, a new speed option has been added: Sync To Audio. This option syncs the emulation to the audio samples. This option can help users that have sound issues like crackling noises or stuttering sound.

- Fixed wrong row/column numbers in Tilemap Viewer when grid is enabled
- Fixed that sometimes the breakpoint console stopped updating
- Fixed that Game Gear ports did not trigger port breakpoints (thanks to sverx and djbass)
This update improves the Sprite Viewer to properly support displaying 8×8 and 8×16 sprites at the same time. It also makes the addresses in the video viewers clickable. A click on an address opens the corresponding address in the Memory Editor.
Other than that, some issues got fixed. The full list of changes follows:
- Improved Sprite Viewer to support 8×8 and 8×16 sprites at the same time
- Made the addresses in the video viewers clickable to open them in the Memory Editor

A minor update of Emulicious, 2020-09-09
- This update adds remote debugging with VS Code. It allows source level debugging with ASM and C code, breakpoints in your own source code and inspection of variables and system state. I’ve already thought about adding external debugging support for some years now but never got around to actually implementing it. So 2 weeks ago I decided to finally look into it and started to implement it. The required VS Code extension can be found on https://marketplace.visualstudio.com/items?itemName=emulicious.emulicious-debugger

A major update of Emulicious, 2020-05-14
This update comes with several additions and improvements. Most notably an additional system is now emulated, the MSX.
Four weeks ago I got interested in emulating the MSX and now I feel it is ready to be released. It supports most cartridge ROMs released for the MSX1. If a disk ROM and an alternative BIOS are provided it also supports program on floppy disks in the form of dsk images.
Emulicious’s debugger now also supports loading Sjasm lst files as source files. Sjasm is a Z80 assembler that is often used for MSX development but can also be used for other Z80 systems like the Mastersystem.
Furthermore, the profiler has been improved to better support the calling convention of C.
The full list of changes follows:
- Added MSX emulation
- Added support to load lst files containing Sjasm sourcecode in the debugger
- Improved Profiler to better work with C calling convention
- Remember last directory for loading sources/symbols
- Fixed an issue with breakpoints on ROMs larger than 4 MB (thanks to Antígeno)
- Improved Auto Palette option in Tile Viewer for SMS Mode 4
- Added View menu to Tile Viewer to choose different layouts
- Added Frame Advance to the main emulator (formerly only available in debugger)
- Improved Tilemap Viewer and Tile Viewer support for TMS Modes
- Added CTRL+SHIFT+BACKSPACE as hotkey for Reload ROM
- Added an option to automatically reload a ROM when it changes
- Fixed a bug that wouldn’t allow setting gamepad inputs if there
- are more than 2 gamepads connected (Thanks to Niloct)
- Several minor bugfixes and improvements
A minor update of Emulicious, 2020-04-03
- When using Table Files the Memory Editor now shows all symbols (e.g. [LF])
- Added missing label for the volume of the noise channel of the Mastersystem

- Breakpoints are based on expressions now instead of just addresses.
This improves the use of breakpoints for ROM development

This update comes with several additions and improvements. One of these addition is the emulation of the FM chip of the SEGA Mastersystem. When it is enabled in the menu Options->Emulation->Master System then games supporting this chip will play music on it.
People interested in developing, hacking or researching games will be happy to see the new tabs in the Memory Editor. For the Master System and Game Gear a tab for VDP register and a tab for PSG registers have been added. For the Game Boy and Game Boy Color a tab for OAM and a tab for HRAM have been added. All systems received a Palettes tab in the Memory Editor.
Additionally, the memory tracer (previously only available for Master System and Game Gear) now also supports the Game Boy and Game Boy Color.
Furthermore, the UI of the disassembler table of the debugger has been improved. Its first column now spans the whole width of the table.
Last but not least, the Go To dialogs and the Find dialogs have been improved. The Go To dialogs are now enhanced by auto-completion facilities and the Find dialogs received a history and several search options.
