Black Screen for "Itoi Shigesato no Bass Tsuri No. 1"

[mr-kyubit]

Hey there! I'm having an issue loading the game "Itoi Shigesato no Bass Tsuri No. 1 (Japan)". The ROM seems to load (I get the standard progress bar), but after that I just get a black screen. The SNES core compatibility has been incredible, and so far this is the only game I've had trouble with. I'm using the version included in the No-Intro set, and the ROM works fine on bsnes.

One interesting note: the original game came as a slotted cartridge with an optional memory pack for Satellaview transfers (https://satellaview.fandom.com/wiki/Slotted_cartridge), but so far I've been able to run other slotted cartridge games just fine in the core (ex: "SD Gundam G-Next" and "Sound-Novel Tsukūru"). I realize memory packs are not currently supported in the core, but in principle the game should load without a memory pack. For example, when I open the ROM in bsnes, there's a memory pack option on the main menu of the game, but it's greyed out.

I posted this to the core-bugs channel on the Discord, and wark91 pointed me to a similar ticket they opened back in October regarding two other slotted cartridge games that appeared to have the same issue: #245

Thanks in advance for taking a look at this!
