 ## Patch types
 
-**Hooks** do not directly modify the ROM; they just identify locations within the ROM code. When the emulated code execution reaches a hook, the emulator performs an emulation function. For example, the `BiographySave_ret` hook is located after the code to add a new Hall of Fame entry, and causes the emulator to edit the save file to enable the GS Ball event.

For example, the `Enable_GS_Ball_mobile_event` hook is located after the code to add a new Hall of Fame entry, and causes the emulator to edit the save file to enable the GS Ball event.
 
 Hooks are defined with the `vc_hook` macro, which defines a label starting with "`.VC_`" for the patch template file to use.
 
-**Patches** directly modify the contents of the ROM. This is done before emulation begins. For example, the `print forbid 1` patch modifies an "`and A_BUTTON`" instruction to "`and 0`", so pressing A will not print Unown on the Game Boy Printer.

 Patches are defined with the `vc_patch` and `vc_patch_end` macros; `vc_patch` defines a label starting with "`.VC_`", `vc_patch_end` defines a corresponding label with "`_End`" appended. Between these two macros, the code or data is conditionally different depending on whether or not a patch file is being built.

 **Patch names** are contained in "`[`" brackets "`]`". They are output as-is, without interpreting commands.
 
-Patch names also set the **current patch label**. This is the label starting with "`.VC_`" followed by the patch name, with any invalid characters (not letters "`A-Z`", digits "`0-9`", underscore "`_`", at sign "`@`", or hash "`#`") converted to underscores "`_`". These labels are conditionally defined only when building the patch file with the `vc_hook` and `vc_patch` macros. For example, the patch name "`[fight begin]`" corresponds to the patch label "`.VC_fight_begin`", generated by the "`vc_hook fight_begin`" macro.

+
+Patch names may designate an alternate for the label with an at-sign "`@`". This allows the label in the assembly source to have a more descriptive name, while still reproducing the original `.patch` file. For example, the patch name "`[BiographySave_ret@Enable_GS_Ball_mobile_event]`" corresponds to the label "`.VC_Enable_GS_Ball_mobile_event`" but is output as "`[BiographySave_ret]`".
 
 **Commands** are contained in "`{`" braces "`}`". They are not output themselves, but may produce their own output when interpreted.
