Super 97 (Ver. 1.00) [Ioannis Bampoulas]
- hexion.cpp: used finders and other small cleanups
- powerins.cpp: corrected one sprite ROM for powerinsc
* Added a 'type()' accessor to fs::meta_value
Let's try to hide the nastiness of std::visit() as much as humanly possible
* Changing visitor approach for std::visit() call in fs::meta_value::type()
- Made VRC4 base class extendable for CHR banking, as was done to PRG banking.

-----------------------------------
1993 New 860 in 1 Over-Valued Golden Version Games [Consolethinks]
1995 New Series Super 2 in 1 (Asia) [anonymous]
- Replaced bad program ROMs with dumps with proper page order.
- Updated banking to work with proper dumps.
- Fixed CHR banking from possibly ignoring first writes.
- Added special latching bytes to internal X1-017 RAM.
- Added IRQ support (no games exist that use it).
* Fixed some issues involving fs::meta_description constructing
With the recent change to use std::variant more closely, I noticed a problem where meta_descriptions of type meta_type::String got defaults of type 't'. This was because the templated ctor for meta_description would convert 'const char *' to 'bool'. This change adds another overload to catch 'const char *', along with asserts to catch problems.
In the process I corrected a few meta_description ctors
It is possible that this change does not go far enough. Perhaps the meta_type argument should be removed, and we should instead create distinct ctor types (rather than relying on templates) and specify the precise meta_type in the overload. Or even go further and remove m_type from meta_description, and instead create an overload that calculates meta_type based on calling std::visit on the variant
* Taking this change a bit further, and removing m_type from fs::meta_description; it was superfluous. Also doing some minor C++-ifications
