Interesting find on PC Engine platform w/ Final Soldier...

[PC Engine Fan X!]

If you have the actual PCE Hu-Cards of Hudson Soft's Final Soldier and Final Soldier Special (or a Krizz Everdrive flash cart with both listed roms) + a Tennokoe Bank 2 add-on accessory, both PCE STG titles share the same save file when it comes to saving the high scores for both 2 & 5 minute caravan games. I did not know that and have learned just today that they do so -- interesting discovery/find indeed for the year 2020 on the PCE console platform.

Also with Hudson Soft's Soldier Blade, it does have built-in support for Backup RAM (BRAM) on the PC Engine Duo/Duo-R/Duo-RX + TTI's Turbo Duo as well (as well with the usual PC Engine/Core Grafx I & II along with the appropriate Tennokoe Bank II add-on accessory). There seems to be no BRAM functionality of Hudson Soft's Soldier Blade Special when it comes to both the 2 & 5 minute scoring runs (which is a shame imho). Oh well.

What other PCE STG titles take advantage of BRAM besides the above listed PCE Hu-Card based STG titles of Final Soldier, Final Soldier Special & Soldier Blade?

holy crap, I just realized that I actually DO have Tennokoe Bank 2 at home; I used it to save progress w/ Devil's crush, but it hasn't occurred to my mind to actually check which STG's use it. Might be worth investigating.

Oh you were asking about the BRAM on the Duo, apologies for too quick reading.. I do have Duo as well, but never noticed any extra functionality on the STG games I own (which are mainly arcade conversions). But this is interesting.
