Changes
Added information on ACE snapshot chunk support
5. Winape allows a 4MB RAM expansion to be enabled but doesn't save the additional RAM in the snapshot.
=== BRKC Chunk (ACE) ===
This chunk is written by ACE when some breakpoints are set. When loading a snapshot, the breakpoints found in this chunk are added to the one already installed.

Notes:
1. The condition is expressed using ACE syntax (similar to BASIC with AND/OR/XOR/NOT/+/-/=...).
Allowed additional syntaxes are:
*&, # or 0x for a hexadecimal number.
*% or &x for a binary number.
*AF, BC, HL, IX... for a 16-bit Z80 register.
*A, B, D, IXh, IXl... for an 8-bit Z80 register.
*FlagC, FlagNC, FlagM... for a Z80 flag.
*LineCount for the line number.
*LineCycle for the µs count on the current line.
*MMR for the memory mapping register.
*UpperROMOn for the paging state of the upper ROM.
*UpperROMNum for the selected upper ROM number.
*LowerROMOn for the paging state of the lower ROM.
*LowerROMNum for the selected lower ROM number.
*ASICPageOn for the paging state of the I/O ASIC registers page.
[[Example :]] FlagC AND (HL=DE OR HL=&5000)
=== CPC+ Chunk ===
This chunk is supported by Arnold, Winape and , No$CPC. I am unable to test Ace so I don't know if it supports this chunk or notand ACE. Arnold , Winape and Winape ACE will save the block when Plus configuration enabled. No$CPC will save the block if the Plus features have been unlocked.
