Summary MESS-specific 06294: mz80kj: Enable existing CG with uppercase letters !
Description The "mz80kj" driver currently uses only CG with lowercase letters !

In the MESS driver "mz80.cpp" on lines 356,357 already exists CG with a uppercase letters, but is disabled.
356 // This has a different Japanese set
357 ROM_LOAD( "80kcgj.rom", 0x0800, 0x0800, CRC(7767f11e) SHA1(8dc88d088b2e7d3198bf856bd44d364fb6e5cfa4) )

This CG has the same CRC(7767f11e) as one mentioned on the !
( It looks that the disabled CG is actually from the "MZ-80K2E" version, an alt version of Jpn. mz80k ! )

So, if one would like to use the CG with an uppercase letters, instead of one with a lowercase letters, this is currently not possible.

If we would like to change this, there are IMHO two possibilities:

The one would be to make it possible which CG directly from the "mz80kj" driver menu,
or maybe better, make a new clone driver "mz80k2e" that contains only the CG !

Note: MZ-80K, MZ-80K2 and MZ-80K2E are practically the same, so it should not be a problem.

A little detailed information regarding MZ-80K2E that could solve the dilemma (if there):
Steps To Reproduce
Additional Information I found most mz80k from Jpn. use CG with uppercase letters, what can be also visible on the MZ-80K brochures from the Sharp museum: ,,, there are no lowercase letters visible even on the prototype brochures !

So I wonder, from which mz80k Jpn. version comes CG with lowercase letters !? :-)

You are referring to "small" as lowercase letters and "big" as uppercase letters?
