There is not a way to delete boards entirely from Robotic.

Potential alternatives to sending specific robots a label are the CHANGE command or using loops/COPY BLOCK to wipe the board contents. I don't know if either of those would be easier.

MegaZeux isn't capable of floating point arithmetic yet, so you have to use fixed point arithmetic if you want decimal precision. There are a couple of ways you can do this using shift/multiplication values or separate variables.

Here's an example that uses a multiplication of 1000 to get three decimal digits if you're just trying to print decimal numbers:

set "mzx_speed" to 2
lockplayer
set "spr0_refx" to "playerx"
set "spr0_refy" to "playery"
set "spr0_width" to 1
set "spr0_height" to 1
set "spr0_unbound" to 1

set "x" to 0
set "y" to 0
: "l"
inc "x" by 1953
inc "y" by 1082
put c?? Sprite p00 at "('x'/1000)" "('y'/1000)"
. "print the decimal portion into a string prefixed with 000 and then print only the last 3 digits of each string."
set "$a" "000('x'%1000)"
set "$b" "000('y'%1000)"
* "x=('x'/1000).&$a+-3& y=('y'/1000).&$b+-3&"
wait for 1
goto "l"

Here's an example that gives a sprite 8 bits of subpixel precision by storing the x and y values in terms of subpixels and using signed right shift to floor divide out the subpixels (this is much more useful for sprites due to its better rounding behavior for negative numbers):

set "mzx_speed" to 2
lockplayer
set "spr0_refx" to "playerx"
set "spr0_refy" to "playery"
set "spr0_width" to 1
set "spr0_height" to 1
set "spr0_unbound" to 1

set "x" to 0
set "y" to 0
: "l"
inc "x" by 500
inc "y" by 277
put c?? Sprite p00 at "('x'>>>8)" "('y'>>>8)"
. "actually printing the precision in decimal is a little more involved..."
set "$a" to "000('x'a255*1000>>>8)"
set "$b" to "000('y'a255*1000>>>8)"
* "x=('x'/256).&$a+-3& y=('y'/256).&$b+-3&"
wait for 1
goto "l"

Disabling the overlay has deleted the overlay entirely since 2.80 (released 20 years ago...), so it is possible you are misremembering.

I can't reproduce this bug, but a couple things you could try:

• Disabling audio to prevent MZX from paging during the audio interrupt (music_on=0 in config.txt or as a command line option). The next release will disable paging so if this prevents your crashes, your issue is already fixed.
  
• Increasing the amount of RAM available in DOSBox in the DOSBox config file. 16MB should be more than enough for most games.

I've released a new update to this game (it was originally supposed to be a 5th anniversary update, and then a 10th anniversary update, but I was a few months late...).

Changelog:

• Added keys for opening locked doors. This can be configured with a setting before starting a new game. By default, keys replace slider puzzles.
  
• Objects now display with unbound sprites by default. An optimized version of the original text mode display is still available if preferred (or required for EGA/NDS).
  
• Impulse Tracker music can now be enabled to replace the default OGG music. This should be used where OGGs are too slow, unsupported (NDS), or have filename conflicts (DOS without long filename support).
  
• PC speaker sound effects can now be enabled to replace the default OGG sound effects. This fits the same use cases as the IT music.
  
• Fixed homeworld music transitions for the DOS port (both OGG and IT).
  
• Fixed and reimplemented the ending overhead flying sound effect.
  
• All object character sets have been moved to the extended sets.
  
• All object scripts are preloaded with a counters file now. This can be disabled by renaming or removing xxydata/pregen.ctr.
  
• Objects should be easier to hit with the Cultist form.
  
• The Flashlight and Ghost can be used in more locations and have a visible effect in most of those places.
  
• The magenta hospital palette has been replaced with two new palettes.
  
• Rearranged the hospital rock puzzle.
  
• Probably other minor changes I forgot.
  
• Some new object interactions have been added.
  
• Minor interaction text and script tweaks.
  
• There is new post-ending dialogue accessible by continuing after completing the game for the first time, including three new endings.
  
• Updated the map to be slightly more useful.
