Ntrq Pulsar

Of course you're already aware of it since you provided a 32KB SRAM file with Pulsar. However, I tried using Pular without the pre-formatted SRAM file and of course the screen is blank with only the cursor showing and you can also move it.

I'm only mentioning it because I advise against releasing it like that. For one, eventually the ROM will make it's way into the NES/Famicom ROM archive collection and without that SRAM file, it's useless and other people won't know how to use it and it requires a formatted SRAM file. It could even be years down the road when your site isn't around anymore and it could be impossible to locate a SRAM file.

Also, you're limiting yourself to emulators and the PowerPak with this setup. Some people may wish to make a Pulsar cartridge but it may be impossible unless you can flash the SRAM chip. Alternately, making some type of circuit with a CF card port that loads the SRAM file and internally flashes or loads the SRAM file to the chip.

I suggest reformatting the SRAM from ROM. Pulsar is 128KB PRG-ROM. You can easily expand to 256KB since the MMC1 registers will easily support 256KB.I realize that is probably a difficult operation since you have to be careful in switching SRAM, based on what I read.I really don't understand the SRAM bankswitching too much since I only saw the register docs SOROM which happens to be 16K.

Anyways, that's just a minor nitpick and my views on it.
