Yaba Sanshiro Blog

CartDev, SEGA's official Saturn development cartridge, was becoming unusable — not because it broke, but because the DOS-and-SCSI world around it did.

I rebuilt the emulation of the Sega Saturn’s background processor, VDP2, from scratch.

YabaSanshiro is an emulator that actively leverages the GPU so that SEGA Saturn games run comfortably on modern hardware.

## YabaSanshiro as a Playground for New Technology

I’m a big fan of sim racing games like *EA Sports WRC*, *iRacing*, *Assetto Corsa*, and more.

## Updated Game Selection Screen with Improved Usability

Finally I have finished Cloud backup and Action replay code on iOS version!!!

On November 22, 1994, the Sega Saturn was launched.

Finally, Yaba Sanshiro was released in the Apple App Store!

Devices equipped with the Snapdragon 8 Gen 3 chipset, including models like the Galaxy S24 and Redmagic 9 Pro, are experiencing crashes when initiating games.

I have heard complaints from many people about the on-screen D-PAD of YabaSanshiro.

I'm developing and testing a new "Auto backup sync" feature.

I was impressed that the retroid pocket 3+ runs Yabasanshiro at full speed.

Handheld game devices are around the world!

I added improvements suggested by user feedback.

I obtained [AYANEO NEXT](https://next.ayaneo.com/) and test YabaSanshiro and fix bugs.

SEGA Saturn has two CPUs.

[Ayn Odin](https://www.ayn.hk/Odin/) is a handheld android device for gamers.

Nvidia Shield TV is upgraded to Android 11.

Currently, Yaba Sanshiro 2 crashes when you run it on Android 5.0, 5.1 and 6.0 , Because these device does not support Vulkan.

They say CHEAT function violates the Device and Network Abuse policy and sections 4.8 and 4.9 of the Developer Distribution Agreement

In the investigation for issues like [#679](https://github.com/devmiyax/yabause/issues/679) and [#664](https://github.com/devmiyax/yabause/issues/664), I found strange behaviors in SEGA Saturn emulation of Yaba Sanshiro.

I've been implementing the new dynamic recompile CPU emulator for ARM64v8a.

Recently I'm trying to develop the new graphics emulation core using Vulkan.

I rewrite almost of the shader code.

Yaba Sanshiro has the cloud save data function.

Since backup data occasionally get broken, you need to back up your backup data.

'uoYabause' got banned, I need to change the name.

I've hacked the Backup library in SEGA Saturn. and succeeded to increase internal backup memory from 32KB to 8MB.

The most irritable thing when I use an emulator on Android devices is **transferring game files to the device**.

New cpu core is now ready!

Yabause has two CPU emulation options.

I don't know why, but I received many requests about cheats support. so I've Implemented it.

* Improve onscreen touch pad.

### Improving Framebuffer Emulation

I fixed many bugs in SCUDSP emulation.

I know SHIELD TV is the only android device which can run uoYabause 60fps and I think it needs a help for other devices.

Important bug fixes

iOS version of uoYabause is updated.

Recently I focused on developing iOS version of uoYabause.

Now, multiple discs are supported!

Minor bug fixes

I've succeed to boot Grandia!

the new sound emulation engine implemented by d357.
