MAMEDev recently applied a patch of mine (thanks to Miodrag) to MAME 0180. It exposes render_target::view_name() so my showcp plugin can check the name of the view before toggling.
Here is the new script:
-- license:BSD-3-Clause
-- copyright-holders:Ben Baker
local exports = {}
exports.name = "showcp"
exports.version = "0.0.2"
exports.description = "ShowCP plugin"
exports.license = "The BSD 3-Clause License"
exports.author = { name = "Ben Baker" }
local showcp = exports
function showcp.startplugin()
emu.register_pause(function()
local target = manager:machine():render():targets()[0]
if target:view_name(1) == "Show CP" then
target.view = 1
end
end)
emu.register_resume(function()
local target = manager:machine():render():targets()[0]
if target:view_name(1) == "Show CP" then
target.view = 0
end
end)
end
return exportsYou can see based on this 1942.lay file how the view name is referred in the xml:
<?xml version="1.0"?>
