KiddEd Major Update Release + Romhack Competition

A major update of KiddEd has been released!

With this new version you can now finally have individual metatilesets for each level. That means you can change the metatileset for one level without affecting the metatileset of any other level. This allows for much more variety and flexibility in the level design.

Furthermore, you can now change the priorities of sound effects in the Sound Editor. These priority is considered when a sound effect is triggered while another sound effect is playing.
In this case, the new sound effect will only play if its priority is equal or higher to the priority of the sound effect that is currently playing.
The new sound effect will then cancel the current sound effect and start playing instead.
For music you can now setup whether a song should loop or not (only works with the PSGlib Sound Engine).

The archive now contains two additional files (you will also get these via the automatic update system):

  • Entities.txt – contains a mapping between entity numbers and entity names
  • Triggers.txt – contains explanations on how the different triggers work

Romhack Competition

For this year’s competition SMSPower also allows romhacks as entrants to the competition. If you’re working on a romhack using KiddEd it would be great if you could join the competition. Otherwise you might still be interested in at least checking out what others are creating with KiddEd.

KiddEd Major Update Release

A major update of KiddEd has been released!
For Windows users that don’t have Java installed on their system an alternative download including Java binaries has been added to the Downloads on KiddEd’s page.

The update comes with several improvements. Many bugs have been fixed.

A first draft of a Physics Editor has been added. It allows editing the physics of Alex Kidd.

Hitboxes can now be selected for every sprite. They can be edited with the new Hitbox Editor accessed from the Sprite Editor’s Edit menu.

The Sound Editor has been improved. It allows importing VGM files directly now and can export to PSG format. Besides that it allows adding new music slots, so for example you can use different songs for each level.

A french localization of the GUI has been added (translation by Revo). You can find it in Settings->Language.

Small update released

A small update has been released. A log has been added to the Breakpoint Window. All breakpoints that get hit will be logged there. By disabling the check for „Suspend“ you can avoid suspension when breakpoints are hit and only log them instead.

Download issues solved and update released

Some people have experienced issues downloading files from These issues should be solved now. If you still encounter problems with downloads from this website please report them so they can be solved as soon as possible.


An update of Emulicious has been released. The update comes with additional options for the tracer and introduces an outline to the debugger.
The outline helps you navigate through code more easily by providing a structured representation of the code. It is directly linked to the selection of the debugger so it can also help to orient yourself in the code.
The tracer can be controlled using conditions now.  You can define conditions on which to start/end tracing and a condition on which to trace an instruction at all.
Besides that the tracer allows you to provide an expression to be evaluated before each instruction being traced. The result of the evaluation is appended to the trace. This way you can add additional information to your trace. For example if you want to watch the value in RAM at $c000 you can set the expression to „@$c000“. Using this expression each line of your trace will also show you the value at $c000.

Emulicious Major Update Release

A major update of Emulicious has been released!
For Windows users that don’t have Java installed on their system an alternative download including Java binaries has been added to the Downloads section.
It comes with several new features:

  • The stack now shows labels of the functions that have been called (it can be double-clicked to navigate to the call)
  • The stack now shows the names of the registers that have been stored in it
  • Conditional breakpoints
  • An option for setting uninitialized memory and a breakpoint that breaks on access of uninitialized memory
  • A breakpoint that breaks when an interrupt doesn’t restore the state properly
  • Emulation of PAL for the SEGA Master System
  • Emulation of the screen borders of the SEGA Master System
  • Options to unhide the offscreen area of the SEGA Game Gear
  • DATA labels in the Z80 disassembler
  • RAM labels in the Z80 disassembler

Besides these new features Game Boy emulation has been fixed and the expressions panel has been improved to support more complex expressions.

Z80 disassembler / Master System disassembler

The Z80 disassembler / Master System disassembler has been improved to create DATA labels for data that is referenced. This can help to identify blocks of data more easily. It now also create RAM labels that can help to determine RAM usage and variable sizes.

Expressions/conditions support the following

arithmetic operators: +, -
boolean/logical operators: &, |
shift operators: <<, >>
compare operators: =, ==, !=, <, >, <=, >=
decimal numbers
hex numbers (prefixed by either $ or 0x)
binary numbers (prefixed by %)
symbols loaded from a symfile
variables (see below)
the @ operator to „read“ a value from a calculated address.

Besides that the following variables are supported:
All register names. As single registers and as register pairs.
va (the current vdp address)
scanline (the current scanline)
address (the current address)
bank0 (the bank in slot 0)
bank1 (the bank in slot 1)
bank2 (the bank in slot 2)
For read/write watchpoints only:
value (the value being read/written)
source (the address being read/written)
For write watchpoints only:
oldvalue (the value being overwritten)

Another update of Emulicious has been released

A new version of Emulicious has just been released.

The new version extends the debugger with a Find Dialog and helps you track the control flow by highlighting the trace of the instructions being executed. A Reference Hierarchy has been added that lists all references to a specified label.

When hovering a control flow instruction its destination will be highlighted now and when it is clicked while holding the CTRL key the debugger will be scrolled to its destination.

A new update of Emulicious has been released

A new update of Emulicious has arrived!

With this new version you can finally enjoy your favorite games in fullscreen! You can enter fullscreen by either pressing ALT+ENTER or from the Graphics menu.

The debugger has been extended by watchpoints (aka memory breakpoints) that will halt execution on a read/write of a specified memory location.

The memory editor has been extended by a find dialog that allows searching the memory. Besides that the memory editor now supports simple table files.
