Coin-Op Collection Announcement: 2025 Roadmap
🕑 Added 2024-11-08 19:00:16 +0000 UTCI’d like to take a moment to share some updates on our plans and current progress as the Z/Y-Unit cores are coming to a close. While we have additional projects slated that aren’t listed here, the summary below should give everyone a good sense of where we’re headed and what to expect.
There’s a lot to digest, so please take the time to read through everything. Darren, Pramod, Brandon, and I will be sharing updates about each project as development continues to keep you informed. Thank you to all of our supporters. Without you, none of this would be possible!
Open-Source FPGA Framework
Our FPGA framework will be open-source and is designed to simplify the creation of a "game core," offering web-based GUI utilities and templates for streamlined configuration. It features variable SDRAM and PSRAM controllers for flexible memory management, making it ideal for diverse 32-bit FPGA platforms. Created with versatility in mind, the framework will support multiple platforms, starting with the Analogue Pocket.
We're dedicating November and the early part of December to framework development and then we'll move forward with open-sourcing the code and a few examples. Some may be old, some may be new!
Framework Overview:
• High performance SDRAM and PSRAM controllers for more intensive memory-demanding cores
• User-friendly web-based tools provide a visual interface for configuration, offering a solid starting
point for building and customizing a game core
• Easy-to-use and reconfigurable framework for post-template generation, adaptable for growing
needs such as multi-platform and peripheral/device support
• Easy-to-follow video tutorials and comprehensive documentation to guide new users through
usage and core creation, with the flexibility to expand and add content as needed
Upcoming FPGA Development
Our FPGA implementation roadmap is outlined below. This should clarify what our "major" projects and plans are for 2025. We have additional open-source FPGA cores planned, which, while not as popular as the development highlights listed, are definitely worth the time to research and develop.
Capcom ZN-1 FPGA compatible Verilog core
Brandon is steadily making progress on his ZN-1 hardware implementation. This month, he'll be wrapping up the remaining schematic extraction for the main motherboard. Below, you'll find progress on schematic extraction and gerber files for the main motherboard, along with the completed schematics for the ROM board. Brandon has completed tracing his die shot image of the DL-3129 and has extracted schematics for it as well. We've decided to follow this process for all future schematic extractions, which will include gerber files, whether done in-house or outsourced to a reverse engineering company.
The reverse engineering company we plan to use for the CPS-III project successfully extracted the FPGA bitstream from the CPDL (Altera EPM7032) on the ZN-1 main board. The next steps for ZN-1 involve writing Verilog and assembling the hardware architecture within our new framework. Once completed, this implementation will branch out to several other Sony-based arcade platforms. We'll update you on the progress of ZN-1 over the winter.
Hardware Overview:
• Sony CXD8530BQ (CPU, R3000A-compatible)
• Sony CXD8561Q (GPU, Toshiba)
• Sony CXD2922CQ (SPU)
• Zilog Z80 CPU (Sub-CPU)
• DL-1425 (DSP, QSound)

Capcom CPS-III FPGA compatible Verilog core
We've already begun our own research and development for CPS-III hardware, below you see our die-shot images of each ASIC for routing and tracing.
The DL-3229 will need to be reimaged as it cracked during the process. Brandon Arnold is spearheading the reverse-engineering process, working closely with a company that specializes in reverse engineering.
Not only will we be providing our own schematics, we'll also be including gerber files for the PCB and security cartridge. Pramod and I will start writing Verilog this winter and alternate between Toaplan V2, T-Unit, and CPS-III.

Midway T-Unit / Wolf Unit FPGA compatible Verilog core
Development for the T-Unit hardware has begun. Upon completing the T-Unit ADPCM hardware variant, Pramod will implement the DCS sound system DSP, which is also used for audio playback in a wide range of Williams and Bally pinball machines.
We estimate it will take roughly 30 to 45 days to complete the ADPCM variant and 90 days to reverse engineer and implement the ADSP2105 DSP. Once the T-Unit is finished, we will begin work on the DMA handler and hardware configuration for the Wolf Unit hardware.

We've completed the majority of development for Toaplan V2 hardware; however, some components still need to be modeled, namely the NEC V25. We’ll be revamping the core structure, implementing the dual GP9001 design, and leveraging the SDRAM and PSRAM controllers from our framework to improve memory bandwidth, with the missing components to be modeled in Verilog.
Hardware Overview:
• Motorola M68000 (Main-CPU, board dependent)

Often, I see people mention Namco Pre-86 and Namco86 hardware. Mr. X was kind enough to share his source code with me and other MiSTer-devel developers. To date, none of those with access to the original source code have released Pac-Land.
We stepped aside after seeing another developer state they were creating the Namco86 core back in January of this year. Since that hasn't surfaced, and we had other ongoing projects, we've moved on.
I, in turn, passed the original source to the author of OpenGateware, boogerman, who successfully ported it. He plans to release Pac-Land after resolving issues and making optimizations to the port.

Working on the TMS34020 to support flip in Twin Cobra and then we'll debug Flying Shark.
Kent Pendragon
Thank you for all the awesome work you've already done — and for an exciting roadmap! 🔥🔥🔥 If possible, native/built in 'Taito Egret II Mini Paddle & Trackball'-controller support in Ghox would be wonderful. And pre-Merry Christmas to all of you.
Michael Johnson
Great stuff guys and thank you for the detailed roadmap - is flying shark still on your radar? will keep my support going as long as you guys still have the desire so rock and fucking roll on 👍
Stove Chops
Much love, keep rocking <3
Zub-Zero
Bravo...This is exciting!
derFunkenstein
Very excited about the Midway boards. NBA Jam TE arcade and UMK3 are huge! Hope they run on the Pocket.
hyp36rmax
LFG! Great job guys.
rester159
yes thank you
atrac17
Whatever is on our roadmap will make it to the MiSTer platform if viable. Does this answer your question?
rester159
all true but Analog pocket can't do ZN-1 (I think?) and Mister is by far the most widespread platform (incl. Taki's new devices). I'm all about offering your work on multiple platforms - as long as it also comes to Mister :)
atrac17
Hi! Thanks for joining as a patron a few minutes ago. Whatever is on our roadmap will make it to the MiSTer platform if viable. There is also the Analogue Pocket and upcoming boards like MARS, Replay2, a new platform (MiSTer?) from Taki Udon, and even a successor to OpenFPGA. From what I've seen on YouTube from FPGA news channels, there is even a MiSTer2 coming, featuring the unreleased DE25-Nano, with MiSTer developers involved!
rester159
will all of these core come to the Mister?
80's spaceman
Wow! I have no words for this.
