WonderSwan Flash Masta – Another Batch Ready To Ship

WS Flash Masta Latest Batch

We have just completed another batch of WS Flash Masta cartridges! As I mentioned last time, these have been very popular, and they sell out quickly when we list them. We are trying to make batches more frequently and in larger quantities. Last time they sold out in a matter of hours, so I hope these last a bit longer. There’s also a coupon code below, if you also want a Neo Geo Pocket flash cart.

We just added a new option and changed the pricing to reflect that. We now offer the cartridge as a PCB only, pre-installed into a shell, and pre-installed with a dust cover.

Note that the “Circuit Board Only” option will need to be installed into a plastic shell. You can use one from another game you already own, but you’ll need to shave/cut some of the plastic (for example to make an opening for the USB and some other parts).

We ran this same add-a-NGPC-cart promotion last time, so I’ll just copy/paste that coupon code and text here.

I know that some of you are wanting to purchase a Wonderswan flash cart AND a Neo Geo Pocket flash cart. As an added incentive, we’ll give you $10 off if you purchase them together! To get $10 off of your order when you purchase a Neo Pocket Flash Masta WITH your WS Flash Masta, please use the following coupon.

WS Flash Masta v5.1 / Looking For 10 More Early Adopters

We are getting close to calling this version ready for full release. We would just like to have some more people play with it a bit before we call it good.

If you’d like to be an early adopter AND you’re in the USA, please use this button to get yours before the official release. The 10 units have been sold. We will be working to validate these units and then move on to full production (assuming things go as expected).

We are limiting this first batch to USA purchases, just in case we need to recall them. We definitely do not expect to have any problems, but we just want to limit the impact in case we do need to fix something. So far, we have a handful of these in testing, and we haven’t heard much negative, yet.

Don’t forget to add a Wonderswan headphone adapter to your order, if you need one.

If you are interested in compatibility, so far we haven’t found anything that worked on the previous v4.4 cartridge that fails on this new v5.1. You can read a bit more about that on our WS Flash Masta v5.1 forum thread. https://forum.freeplaytech.com/showthread.php?tid=5139

For users, this new v5.1 should work the same as the v4.4. It doesn’t add any new playability features. Here are the new benefits:

  • Cartridge Shell – The cartridge circuitry now fits inside of a modified WS cartridge shell.
  • Battery – The cartridge no longer relies on a battery to store savegame data, so you won’t ever need to replace a dying/leaking battery.
  • Manufacturable – The previous versions of the cartridge were troublesome to source parts for and difficult to assemble. This v5.1 version should be much easier to keep in stock, so we don’t have to trickle out tiny batches of carts sporadically and annoy people that miss the opportunity to buy.
