Now i will single file "U-Boot" another unexpanded game that use 2 part, the first one for instructions and for load characters in memory from $1c00 to $1c9f and the 2nd for a small main program.
Now i'm single filed and crunched it but i want to preserve the instruction writed in basic in the first part.
After loading the crunched program the LIST is:
Now i will to add some line, so the result is:
Code: Select all
1 PRINT"U-BOOT DO YOU LIKE INSTRUCTIONS ?"
2 GETA$:IFA$=""THEN2
3 IFA$="Y"THEN5
4 GOTO239
5 PRINT"INSTRUCIONS"
10 GETA$:IFA$=""THEN10
239 SYS4109
but on SYS4109 now the program crash because the basic overwrite the $1001> bytes in memory, there is a way to direct the basic from example from $1900? another way to fix this problem?
