fddd390d31 on the C64, if not using floats, disable basic ROM in startup to gain another 8Kb of RAM 
MEMTOP is adjusted to $d000. This gives us 50 Kb of contiguous program RAM space. ($0801-$CFFF)

98570ac456 cx16: optimized sys.set_rasterline() 2023-11-23 00:02:04 +01:00
Irmen de Jong
08ac459a41 breaking change: sys.set_irq() and sys.set_rasterirq() no longer have useKernal parameter! The irq handler routine must return a boolean instead in the A register. 
When it returns true it means run the system IRQ handler afterwards. When it returns false, the system handler is NOT ran afterwards.

a296d26328 api change: renamed cx16.push/pop_vera_context() to save/restore_vera_context() 
this better reflects its capability because it doesn't use a stack, only a single buffer
