The next release is done with :
- '0' prog helper corrected
- accurate timer even at speed greater than x1 (synchronized with android timer)
As it is an hardware emulator it use the published rom of the HP55 from a public patent.
To add features, you are free to use the 4 256 words pages not used in the current rom to code some patches over the HP rom.
I already done this kind of stuff for the HP97 rom (to add 5 new opcodes and extending the memory) but I won't do it for the HP55 rom ... too time consuming for a basic calculator.
For the HP97 it goes from 26 regs and 224 steps to 106 regs, 896 steps and a new 'e' index register (see LINK )
P.S. sorry no iOS release (search for an old post where I explain why ...)
P.P.S for go29c, I need the rom :(
P.P.P.S in the meantime, there is a go38c for bean counters ;)
