My list for more Cave shooters on Mister is strong

Damn i cant wait for more Cave Shmups.

Total need = IBARA, Mushihimesama, Deathsmiles, Akai Katana

Cheers

Air Gallet is an absolut stunning vertical shmup.
The Shuttle launch at the end of the first stage is so unique.
Never seen such a great scrolling effect in a other game.

Big need für Arcade Nerds

Forget about these games. They have nothing to do with the Cave 68000 and the hardware behind them is much more powerfull, beyond the limits of the De10 Nano I'm afraid.

Oh ok.... thanx for the technical explanation

Kind regards

Will more cave shooters be on the Mister someday? Like Ibara Black Label, Ketsui and so on

Will there be once a core for the SH3 System Cave shooters

I wrote that they are not possible. Right? PGM System too?

Cave CV1000B/D should not be possible:

http://www.system16.com/hardware.php?id=961

However, the PGM "might" be possible and it has some CAVE games:

Will be onetime a new mister pcb with better cpu for more cores likes this one or ps2?

AS the complexity of the HW increases such as the processor or the GPU the effort needed expands raapidly to more than 1 perosn can reasonably handle. If you want modern systems go to SW emulation. Even the PS2 is vastly more complicated than the PS1 and would probably take a team of developers

From RAKI´s patreon:

"Possibilities for CV1k

A lot of people are wondering if the CV1k will move on the MiSTer, and I'll do a little research on the specs of that board and tell you what I've concluded for now.

1. There is currently no FPGA platform that can run it.

2. It might be possible on a MiSTer with dual SDRAM at >133MHz.

3. The Pocket doesn't have enough VRAM capacity.

4. The biggest problem is the SH3. The j-core SH2 is nice, but it's written in VHDL(we can accelerate Verilog simulation by using Verilator), and I'm not sure it can reliably run at 103MHz on the worst Cyclone V silicon. I'll have to make a SH3 core with care. The manual is about 800 pages long. I don't have to read it all, but it's going to take me a long time if I make it myself.

5. The game program on the CV1k is stored on NAND flash with 70ns access time, and the main RAM is an SDRAM(32-bit) at 50MHz. MiSTer DDR3's Latency is unpredictable, but fortunately, we can send a wait signal to the CPU. Even if I were to store this on DDR3, the cache miss penalty shouldn't be too bad if I implement a 2-way L2 I-Cache.

6. Currently I don't know the bandwidth of the MP2 sound player, but it should be able to fit on DDR3.

7. The biggest bandwidth Moloch on the CV1k is the DDR VRAM. The original board used 32-bit DDR RAM clocked at 74 MHz. To get a similar bandwidth with the dual SDRAM, we would need to run it at >148 MHz. However, these numbers are not "absolute". Unlike old PCBs like the Darius II, the blitter can send wait instructions to the main CPU. By lowering the VRAM clock, the CPU will wait longer for the blitter command to be done. A veteran shmup player will notice this in certain scenes, but I don't think it'll be terrible.

This is a pretty challenging system for a consumer-level FPGA platform, even if it wasn't state-of-the-art at the time. It's a good thing the CPU isn't an OoE superscalar RISC. But still, MMU will be tricky to implement. I've made CPUs a couple of times and the task itself isn't that hard. An SH “core” that just executes instructions without interrupts, exceptions, or bi-endian consideration would be easy to make, but it would take more time to decorate around it with peripherals. "

So atleast RAKI will look into the possibility for a MISTer core.

The PGM is possible, right? There's some good games on that.

Ketsui, DDP DOJ, ESPGaluda, Demon Front...
