=== Wrong assembly instructions === These are fixed in Eryk's patch mentioned above. The assembly instructions for various levels is incorrect, some instructions that are bugged include, but are not limited to: * Store and load instructions (including pload and pstore) * Move, neg, and not instructions * Push and pop instructions * Call and return instructions Several of these have the wrong Mode, wrong OPcode, are simply outdated, or the description contains an error . Below shows the correct instructions for these functions. You can either change them in game or in the meta.txt file associated with the level.<syntaxhighlight lang="text"> load8 %dest(register), %address(register) 01100000 dddd0000 0000aaaa 00000000 Loads %address from RAM and stores it to %dest store8 %address(register), %value(register) 01100001 0000vvvv 0000aaaa 00000000 Store %value to %address in RAM load_8 %dest(register), [%address(immediate)] 01110000 dddd0000 aaaaaaaa aaaaaaaa Loads %address from RAM and stores it to %dest store_8 [%address(immediate)], %value(register) 01110001 0000vvvv aaaaaaaa aaaaaaaa Store %value to %address in RAM load16 %dest(register), %address(register) 01100010 dddd0000 0000aaaa 00000000 Loads %address from RAM and stores it to %dest store16 %address(register), %value(register) 01100011 0000vvvv 0000aaaa 00000000 Store %value to %address in RAM load_16 %dest(register), [%address(immediate)] 01110010 dddd0000 aaaaaaaa aaaaaaaa Loads %address from RAM and stores it to %dest store_16 [%address(immediate)], %value(register) 01110011 0000vvvv aaaaaaaa aaaaaaaa Store %value to %address in RAM pload8 %dest(register), %address(register) 01100100 dddd0000 0000aaaa 00000000 Loads %address from SSD and stores it to %dest pstore8 %address(register), %value(register) 01100101 0000vvvv 0000aaaa 00000000 Store %value to %address in SSD pload_8 %dest(register), [%address(immediate)] 01110100 dddd0000 aaaaaaaa aaaaaaaa Loads %address from SSD and stores it to %dest pstore_8 [%address(immediate)], %value(register) 01110101 0000vvvv aaaaaaaa aaaaaaaa Store %value to %address in SSD pload16 %dest(register), %address(register) 01100110 dddd0000 0000aaaa 00000000 Loads %address from SSD and stores it to %dest pstore16 %address(register), %value(register) 01100111 0000vvvv 0000aaaa 00000000 Store %value to %address in SSD pload_16 %dest(register), [%address(immediate)] 01110110 dddd0000 aaaaaaaa aaaaaaaa Loads %address from SSD and stores it to %dest pstore_16 [%address(immediate)], %value(register) 01110111 0000vvvv aaaaaaaa aaaaaaaa Store %value to %address in SSD cmp %a(register), %b(register) 00101001 1111aaaa 0000bbbb 00000000 Compares %a and %b and store the resulting flags in r15. cmp %a(register), %b(immediate) 00111001 1111aaaa bbbbbbbb bbbbbbbb Compares %a and %b and store the resulting flags in r15. mov %a(register), %b(register) 00100100 aaaabbbb 00000000 00000000 Copies from register %b to register %a mov %a(register), %b(immediate) 00110100 aaaa0000 bbbbbbbb bbbbbbbb Copies immediate %b to register %a neg %a(register), %b(register) 00100101 aaaa0000 0000bbbb 00000000 Negate register %b and store the result in %a not %a(register), %b(register) 00110110 aaaabbbb 11111111 11111111 Bitwise NOT each bit in register %b and store the result in %a push %a(register) 00110101 11101110 00000000 00000010 01100011 0000aaaa 00001110 00000000 Pushes %a on to the stack.
