FYI, I have also added Custom Shields & Custom Jobs patches in WARP and yes it supports all clients from 2010 - 2021. New features
Maximum Shield count can be customized now (limited to 127 for now).
You can also validate a shield id based on the job id by modifying ValidateShieldID function in ShieldTable_F.lub.
All the Lua files are now in a different folder called 'JobInfo' to avoid mixing in with others.
The tables have gone through some changes as well.
You can specify different strings based on servicetype. For e.g. "korea" and "america" can have different strings.
To achieve this, you need to specify an override table with the name LT_<servicetype number>.
For e.g. LT_0 specifies overrides for korea servicetype. Check PCNames.lub to get a clearer idea.
At present it is only used for name changes & palette path changes.
Scaling for Baby Jobs can be changed. You can change this in Shrink_Map inside PCIDs.lub.
There is one caveat though, due to client limitation, the factor needs to be specified as an IEEE hex string.
(no floating point support in Lua function calls )
You get the option to copy the files to your patched client area. The files are copied only if you apply the patch.
For Custom Shields, the max shield value also gets updated in the copied file automatically.
I was planning on more amount of changes in Custom Jobs, but it's on hold for now.
