memory map (c16/+4)
===================
$1000 => $23ff Game code G 1000 (*)
$2400 => $33ff Level data
$3400 => $3fff Graphics data
$1000 => $17ff Turbo tape loader G 1008 (**)
$1000 => $14ff Level editor G 1008
$2000 => $2aff Multi-color mode character editor G 2000 (***)
(*) The VICE Emulator has problems with the screen scrolling
code used in this game, another emu must be used.
(**) Tape loader also contains high score maintenance
code and relocates to low memory.
(***) This version of the graphics editor uses a different
block layout to that used in tomcat. There was probably
a specific editor which hasn't been found, yet.
memory map (+4 only)
====================
$4000 => $47ff Turbo tape utility G 4000
How to reproduce an original tape is as yet unknown at least
until I work it out (reasonable) or remember (unlikely).
notes
=====
Game source requires tvl (ted version low) to assemble
and can only write code to disc as there is not enough
room to assemble to ram.
Game code is 5120 ($1400) bytes in size stored at $1000 => $23ff
Graphics data is 3KB ($C00) in size stored at $3400 => $3fff
Level data is 4KB ($1000) in size stored at address $2400 => $33FF
loader operation
================
1. relocate code
2. load in program and graphics
3. run code
code then loads in level data
