This update comes with additional emulated peripherals.

For the MSX, you can now emulate a joystick or a mouse.

For the Mastersystem, emulation of the Sports Pad, the Mega Mouse and the Paddle Control have been added. Since the official games expect an export Paddle Control to be used on an export system, there is an option to emulate an export Paddle Control. For compatibility reasons, this option is enabled by default. Please note that there is no evidence for the existence of such a Paddle Control other than the code in these games. So if you plan to support the Paddle Control in your own games, you might want to target the Japanese Paddle Control.

The full list of changes follows:

• Added support for function breakpoints set from remote debuggers
• Added emulation of ASCIIX-16 and Yamanooto mappers for MSX (thanks to aoineko)
• Added support for entering expressions when setting register values (thanks to aquacash5)
• Added an option to disable overlays (thanks to sverx)
• Added emulation of the Japanese (and Export) paddle, the Mega Mouse and the Sports Pad for Mastersystem (thanks to sverx and raphnet)
• Added emulation of the Joystick and Mouse for MSX (thanks to aoineko)
• Some minor performance improvements (thanks to KirbyKing)
• Fixed a nasty bug that could cause the profiler to lose track of the call stack (thanks to aoineko, Miguel Angel and slogra)
• Fixed a nasty bug where stepping backwards could go wrong (thanks to ISSOtm and Max The Great)
• Fixed a nasty bug related to (hblank) HDMA (thanks to Biddly and Zumi)
• Fixed synchronization of audio and video in video recordings (thanks to Maxim and Flygon)
• Fixed a bug that could amplify noise in a specific way of playing back samples on Game Boy (thanks to ISO 3166-1 alpha-3 and VtR)
• Fixed a bug related to length counters of the GB sound channels (thanks to Occocc)
• Fixed missing stereo output in recordings (thanks to Maxim)

Today’s update adds a new feature to Emulicious: Overlays

You can find this new feature in the Overlays tab at the bottom of the Debugger. It allows you to overlay information on top of the main screen. So you can for example display hitboxes or other shapes on top of your game graphics. Or display some values for debugging directly on screen.

The Overlays feature supports Emulicious’s expression language in each of its textfield columns. So you can either simply use values of variables via expressions like @playerX or more complex expressions like @(hitboxes + @playerHitboxIndex * 4 + 1). You can even make the color depend on specific conditions via something like $ff0000 * (@playerX > 100) + $00ff00 * (@playerX < 150) to use red if player’s x position is greater than 100, green if player’s x position is smaller or equal to 100 and yellow if player’s x position is between 100 (exclusive) and 150 (inclusive). The expression abuses the fact that conditions evaluate to 1 when true and 0 when false. When both conditions are true, both values get added together and form $ffff00 (yellow). If only the first condition is true, we get $ff0000 (red). If only the second condition is true, we get $00ff00 (green). If neither condition was true, we would get $000000 (black).

The Trigger column lets you choose between VBlank, PrevVBlank and Breakpoint. If VBlank is selected, the values are polled when VBlanking begins. For something like hitboxes, by the time of VBlank, the game will already have calculated the player position for the next frame but not updated VRAM accordingly. So if the game values at VBlank are used to display the hitbox, the hitbox will appear one frame ahead of what is actually visible on the screen. To solve this, the PrevVBlank Trigger uses the game values at the time of the previous frame and thus the ones matching what is currently displayed on screen.

Selecting Breakpoint here allows you to use any breakpoint as trigger for your overlay. That way you can display values from at a specific point of your program. For example it allows you to create a custom usage meter by putting a breakpoint on the beginning of your procedure waiting for vblank and use the scanline variable to determine for how many scanlines your program is going to wait until VBlank.

If you find any other creative way to use the new Overlays feature, I’m happy to read about them. 🙂

With yesterday’s update there has been an issue with the automatic update system. This issue should be resolved now (Thanks to Révo).

You can manually update Emulicious now by manually downloading the latest files from this website and extracting the contents of the zip archive into your Emulicious directory, or via Emulicious’s update system.

You can manually update Emulicious by selecting Configure Updates in Emulicious’s Help menu then clicking the Check Updates button then clicking the Update Now button.

Sorry for any inconvinience this has caused.
