Other features of Jace include:
- Small IDE for programming Applesoft basic and Assembly (via built-in ACME cross assembler)
- Built-in terminal with fully integrated monitor and debugger (Apple II-like syntax)
- Cheat features for some popular games like Prince of Persia, Montezuma's Revenge, Wolfenstein and more
- Metacheat feature allows searching memory for discovering new game cheats/mods

This is the default mode when you start the Terminal. It provides access to basic emulator functions.
Commands:
- `monitor` (`m`) - Enter monitor mode
- `monitor` (`m`) - Enter monitor mode (includes all debugging functionality)
- `assembler` (`a`) - Enter assembler mode
- `debugger` (`d`) - Enter debugger mode
- `swlog` (`sl`) - Toggle softswitch state change logging
- `swstate` (`ss`) - Display current state of all softswitches
- `registers` (`r`) - Display CPU registers

### Monitor Mode
Monitor mode allows you to examine and manipulate memory directly.
Monitor mode allows you to examine and manipulate memory directly, and provides all debugging capabilities.
Commands:
- `examine` (`e`) addr [count] - Display memory at address (hex)
- `deposit` (`d`) addr value [value2...] - Write values to memory
- `fill` (`f`) addr end value - Fill memory range with value
Memory Commands:
- `fill` (`f`) start end value - Fill memory range with value
- `move` (`m`) src dest count - Copy memory block
- `compare` (`c`) src dest count - Compare memory blocks
- `search` (`s`) start end value [value2...] - Search for byte sequence
- `find` (`f`) start end value [value2...] - Search for byte sequence
- `disasm` (`l`) addr [count] - Disassemble memory
- `back` (`b`) - Return to main mode
- `help/?` - Show help
- `help/? <cmd>` - Show detailed help for a specific command
- `exit/quit` - Exit the Terminal
Traditional monitor syntax is also supported:
- `XXXX` - Examine 16 bytes from address XXXX
Debugger Commands:
- `pause` (`p`) - Pause emulation
- `resume` (`r`) - Resume emulation
- `cpu` - Display CPU state
- `break` (`br`) addr - Add breakpoint at address
- `break remove addr` - Remove breakpoint
- `break clear` - Remove all breakpoints
- `breakpoints` (`bp`) - List all breakpoints
- `watch` (`w`) addr [name] - Add memory watch (triggers on READ or WRITE)
- `watch remove addr|name` - Remove watch
- `watch clear` - Remove all watches
- `watches` (`ws`) - List all watches
- `cheat` (`ch`) addr value - Add memory cheat
- `cheat remove addr` - Remove a cheat
- `cheat clear` - Remove all cheats
- `cheats` (`cs`) - List all cheats
- `step` (`s`) [count] - Step CPU instructions
- `runto` (`rt`) addr - Run until PC reaches address
- `back` (`b`/`q`) - Return to main mode
Direct Apple II Syntax:
- `XXXX` - Examine memory at address XXXX
- `XXXX:YY ZZ` - Deposit bytes YY, ZZ at address XXXX
- `XXXXG` - Begin execution at address XXXX
- `XXXXL` - Disassemble from address XXXX
- `L` - Continue disassembly from last address
- `XXXX.YYYY` - Show memory range from XXXX to YYYY
- `M/X` prefix - Access main/auxiliary memory (e.g., `MXXXX`, `XXXX:YY`)
### Assembler Mode
@ -95,30 +111,16 @@ Commands:
Any other input is treated as 6502 assembly code and added to the buffer.
### Debugger Mode
Debugger mode provides advanced debugging capabilities.
Commands:
- `break addr` - Set breakpoint at address
- `clear [addr]` - Clear breakpoint(s)
- `list` - List all breakpoints
- `trace on|off` - Enable/disable instruction tracing
- `watch addr` - Add memory watch
- `unwatch [addr]` - Remove memory watch(es)
