On 523aaf1, when a PARv3 code is entered that contains any "Always skip..." lines, those lines are silently dropped after entering.

Example:

0E200000 00000000	Always skip next line
00200000 00000000	[02000000] <- 00
4E200000 00000000	Always skip next two lines
00200000 00000000	[02000000] <- 00
00200000 00000000	[02000000] <- 00
8E200000 00000000	Always skip all next lines
00200000 00000000	[02000000] <- 00
CE200000 00000000	Always skip all lines
00200000 00000000	[02000000] <- 00

E77D3CEF 1E6445A7

E77D3CEF 1E6445A7

After entering in mGBA:

E77D3CEF 1E6445A7
E77D3CEF 1E6445A7
E77D3CEF 1E6445A7
E77D3CEF 1E6445A7
E77D3CEF 1E6445A7

I went back and checked on 0.6.0, too -- which precedes 348b33c. The same behavior occurs there.

At the very least, the "always skip next line" and "always skip next two lines" codes would be quite nice to have, as they let one invert the If-AND code type for PARv3 and create a code that ORs a specific bit. For example:

3820224A 00000001
0E200000 00000000
8020224A 00000001

Though there is another way to achieve that which also uses 3 lines, so it's not a huge deal.

Yeah I never added this because I didn't know if there was much use for it.

Hope I got this right. Let me know and I can reopen it if it's still broken.
