How do I develop a console in Game Dev Story?

Solution 1:

If you have a Hardware Engineer but cannot make a console by going to Develop > Console, you're not in the 3rd office. That option only becomes available once you enter the 3rd office. You will get the offer to go to the 3rd office around the 10-year mark for $25k, and it will be the final office you are offered.

Solution 2:

Buy 6 career change manual from Salesman

Get one employee Coder with level 5.

Apply career change manual in this employee and change your career to Writer.

Level up career writer to level 5.

Repeat this process for all the following careers:

• Sound Engineer
• Director
• Designer
• Producer

Apply career change manual again and Hardware Engineer be able in menu.

Now you can create a console in Develop menu.

Be ready to pay a salary of about 500k for that employee
